Acoustic sensors enable efficient and non-invasive monitoring of a wide range of species, including many that are difficult to monitor in other ways. Although they were initially limited in application scope largely due to cost and hardware constraints, the development of low-cost, open-source models like the Audiomoth in recent years has increased access immensely and opened up new avenues of research. For example, some teams are using them to identify illicit human activities through the detection of associated sounds, like gunshots, vehicles, or chainsaws (e.g. OpenEars).
With this relatively novel dimension of wildlife monitoring rapidly advancing in both marine and terrestrial systems, it is crucial that we identify and share information about the utility and constraints of these sensors to inform efforts. A recent study identified advancements in hardware and machine learning applications, as well as early development of acoustic biodiversity indicators, as factors facilitating progress in the field. In terms of limitations, the authors highlight insufficient reference sound libraries, a lack of open-source audio processing tools, and a need for standardization of survey and analysis protocols. They also stress the importance of collaboration in moving forward, which is precisely what this group will aim to facilitate.

Audiomoth Energy consuption estimates

4 May 2024 4:38am
To start, very interesting project and I think you've ran into a problem that we've all ran into with data logging. On top of that most biodiversity assessments require a continuous recording period to be successful/useful for ACI or SPL, you need an expansive amount of time and space to characterize the biodiversity of a habitat. I suggest here some really easy fixes that would raise your recording periods, while if you would be interested in more complex solutions please reach out to me and I'd be happy to discuss more. I suggest a couple of tactics:
- While you can't time delay, one could set up two at the same location and be recording 12 hours with one and 12 hours with the other. This would rapidly increase your recording duration, but you would want an expansive amount of overlap between the two so you could compare variability and compensate for clock drift. The thing to note here is that hydromoths are not calibrated and highly directional. You can't compare across these devices without characterizing your response by playing back a sound with a known source level to the two recorders at the same distance, especially for acoustic indices which already carry a huge assumption.
- Your rechargeable batteries will often have a significantly lower capacity and comparable to alkaline. Look for the highest capacity, I think Duracell has the highest (8550 mAh). Make sure you check your batteries and it may be worth just going with a reliable brand. From a safety aspect, it may also not be fun/it is dangerous to handle lithium if it were to flood with salt water as they can catch on fire and cause them to explode. In marine research it is not if it will flood, it is when will it flood. For the environmental aspect, always take your batteries to a recycling center. The zinc and manganese in these can be reused and it is a heavy metal that can heavily (pun intended) affect the environment.
- Lower your sampling rate. Unless you're recording marine mammals, it doesn't need to be recording that high and this will give you a lot more days of data and save you on storage space. Additionally, the high frequencies on a hydromoth aren't that sensitive. If you provide a species of interest, I could be more specific, as I too am currently studying bioacoustic biodiversity assessments. I'm happy to collaborate and discuss btw.
- As many have mentioned, SD cards are very power hungry and audiomoth did a clever trick of first storing this on a flash memory and then writing it onto a microSD card... problem being if you start recording too fast without a proper amount of write time, you'll never have data because well it didn't have enough time to write. I would look at utilizing better yet an SD card with low voltage signaling. I think micron is the only one capable right now. I have a feeling that this is where SD card technology will be headed towards for low power devices. I'm only speaking from a theoretical point that this would be the most power efficient. The most power efficient from SanDisk (and microSD card fakes happen all the time, so ensure you get them from a reliable source) is to get the SanDisk Extreme Pro. The reason why it is the best is that this card has a faster write speed meaning it can turn off quicker and use less power. There's other cards out there, so this is all just suggestive.
- Might be odd to hear and maybe unconventional, but cut the LEDs. This will definitely give you more days worth of data, however, you will lose the ability to see if it is recording and your SD card is actually functional, so I would check all your systems before deploying. The LEDs actually utilize a lot of your power and you may even get 1.25-1.5 X the recording duration. I don't have the specifications of the LEDs in front of me, but that's what I have had in my experience.
4 May 2024 12:43pm
Hi Matt,
I measured the consumption of AudioMoth with the LED enabled and disabled, and the difference is pretty negligible at 48kHz, and probably at other sample rates as well. The LED use less than 0.5mA compared to about 30mA for the SD card write, and they are only on for quite a short period - about 30ms at 48kHz.
We found that SanDisk Extreme Pro cards have quite high write currents and they can be more noisy than SanDisk Extreme (red and gold) cards.

Acoustically Transparent Epoxy
26 April 2024 3:26pm
1 May 2024 5:35pm
Same issues here. A MEMS is a great idea to pot, but you really need a piezoelectric element for this to work and not a MEMS based on capacitance (btw they're all capacitance, except for one now discontinued...). It was originally made by Vesper, but the company was bought out last year and the MEMS is no longer made.
This is because you're no longer really doing a typical microphone, this would be a contact type hydrophone. For waterproofing, you can actually get a waterproof MEMS. As long as your not submerging this for an extended period, it should do the job. Be sure to keep the cable short between the PCB and the mic as you'll get noise as I've experienced.
For generally answering your question on the "best" epoxy to with sound transparency, in general the harder the material the lower the acoustic impedance. I use Epotec 301 resin with a hardness of 85. Your shape will also influence the resonance frequencies, meaning the flat frequency response will now be distorted and you'll probably have distorted audio. .
3 May 2024 1:25am
You generally don't want to pot MEMS microphones since they're designed to pick up on air pressure changes and adding any material in front of the microphone just introduces another transition layer where pressure waves need to propagate through. Also, potting the MEMS microphone can be tricky since if you get any material in the port, you could damage the microphone or drastically reduce its performance. If you want to seal something with epoxy, take a look at contact microphones. Higher frequencies will be attenuated but depending on the application, it could work.
There are companies, however, that design fabrics that are waterproof/resistant but have a relatively low acoustic impedance. SAATI has a variety of samples that you can request and GORE makes Acoustic Vents that could work. You can design a mechanical housing around your MEMS microphone with small perforations that are covered by one of these materials. I did this for one of my latest projects and it holds up just fine in heavy rain conditions.
3 May 2024 5:34pm
Hi Jesse,
For a material to be acoustically transparent (in air), the speed of sound in the material times its density must match that of air. Realistically, any solid material will have a greater density than air, and a higher speed of sound to boot, so I'm afraid there's no way to match it to air. Sorry.
WILDLABS AWARDS 2024 - Developing AudioMoth for the detection of infrasonic elephant rumbles
11 April 2024 7:35am
11 April 2024 4:05pm
Awesome project!!
2 May 2024 6:24pm
Very interesting project! I had a few questions or things to consider. Funny enough, I work next to the Elephant Listening Project (ELP) in Central Africa. They've tried a few things to capture infrasonic sounds from these guys like with geophones, mics, and hydrophones, but while successful in Savannah elephant species, the dense forest and ground structure in Central Africa from my understanding increases the acoustic impedance and presented a challenge. Besides ground type, I'm also curious if there are differences in infrasonic vocalizations of Asian versus Central African elephants to consider? I think they'd be a great group to collaborate with, if you haven't reached out already!
The other question I had is if you're thinking of hardening the case? From what I've seen, elephants will break/play anything they find new. The acoustic swift team had to make a custom case for them so the elephants have a "less" likely chance of breaking them. Below is an example of a tusk versus a Pelican we keep around.
3 May 2024 4:58pm
@Andrew_Hill Amazing project and something I have been looking into as well. I do human-elephant conflict work in Asia mainly in Sri Lanka. I am using a series of Audiomoth to collect vocalizations and conflict data. It would be great to chat with you and maybe collaborate if you want to test them with Asian elephants in the field.

Drop-deployed HydroMoth
2 April 2024 10:20am
15 April 2024 6:53am
Hi Matthew,
Thanks for your advice, this is really helpful!
I'm planning to use it in a seagrass meadow survey for a series of ~20 drops/sites to around 30 m, recording for around 10 minutes each time, in Cornwall, UK.
At this stage I reckon we won't exceed 30 m, but based on your advice, I think this sounds like not the best setup for the surveys we want to try.
We will try the Aquarian H1a, attached to the Zoom H1e unit, through a PVC case. This is what Aquarian recommended to me when I contacted them too.
Thanks for the advice, to be honest the software component is what I was most interested in when it came to the AudioMoth- is there any other open source software you would recommend for this?
Best wishes,
Sol
21 April 2024 7:10pm
Hey Sol,
No problem at all. Depending on your configuration, the Audiomoth software would have to work on a PCB with an ESP32 chip which is the unit on the audiomoth/hydromoth, so you would have to make a PCB centered around this chip. You could mimic the functionality of the audiomoth software on another chip, like on a raspberry pi with python's pyaudio library for example. The problem you would have is that the H1A requires phantom power, so it's not plug and play. I'm not too aware with the H1e, but maybe you can control the microphone through the recorder that is programmable through activations by the RPi (not that this is the most efficient MCU for this application, but it is user friendly). A simpler solution might be to just record continuously and play a sound or take notes of when your 10 min deployment starts. I think it should last you >6 hours with a set of lithium energizer batteries. You may want to think about putting a penetrator on the PVC housing for a push button or switch to start when you deploy. They make a few waterproof options.
Just somethign else that occured to me, but if you're dropping these systems, you'll want to ensure that the system isn't wobbling in the seagrass as that will probably be all you will hear on the recordings, especially if you plan to deploy shallower. For my studies in Curacao, we aim to be 5lbs negative, but this all depends on your current and surface action. You might also want to think about the time of day you're recording biodiversity in general. I may suggest recording the site for a bit (a couple days or a week) prior to your study to see what you should account for (e.g. tide flow/current/anthropogenic disturbance) and determine diel patterning of vocalizations you are aiming to collect if subsampling at 10 minutes.
Cheers,
Matt
3 May 2024 12:55pm
Hi Sol,
If the maximum depth is 30m, it would be worth experimenting with HydroMoth in this application especially if the deployment time is short. As Matt says, the air-filed case means it is not possible to accurately calibrate the signal strength due to the directionality of the response. For some applications, this doesn't matter. For others, it may.
Another option for longer/deeper deployments would be an Aquarian H2D hydrophone which will plug directly into AudioMoth Dev or AudioMoth 1.2 (with the 3.5mm jack added). You can then use any appropriately sized battery pack.
If you also connect a magnetic switch, as per the GPS board, you can stop and start recording from outside the housing with the standard firmware.

Vinegar is also a great solution! Let it sit overnight and then just scrub it off. As a warning if you don't clean it, your sensitivity does decrease. You might actually see this if you keep it out there for a month that the amplitude of your calls decrease over the month/you might detect fewer calls.
1 May 2024 5:51pm
Hey! I would recommend a few things:
1) set up at least two in the same site kind of back to back or side to side if you have that many. Directionality can influence the number of calls you get and it's just good to know your error rate.
2) Experiment with breaks and recording duration. You wont collect anything if the write time is not long enough to record to your SD card and you'll get empty files.
3) Clean your device every time you take it out or see visible biofouling. Also, add silicon grease every time to your O-ring. Take it out with an O-ring pick and clean the plastic seal, looking for any type of sand/mud/debris. We've had a few flooding incidences, but this is probably because we open them all the time.
4) lower the frequency rate the more data you can collect, so keep it as low as your frequency of interest without clipping your calls. Fish are lower than pretty much everything (2kHz-3kHz).
I hope this helps!
2 May 2024 6:45pm
Oh wow, thank you so much!!!
I will keep that four advices in mind!

Hi Ian,
I have hours of an unidentified creature recorded during overnight recording sessions with mutliple hydrophones. We think it is platypus but there is nothing to compare against that isn't from captive sounds. I am waiting on the Hydromoth to become available again so I can do longer term monitoring.
1 May 2024 5:26pm
Hi everyone, I just got my first hydromoth and wanted to test it for aquatic soundscape with interest in Tomistoma, Otter, boat traffic and maybe fishes too! But before that I maybe test it on zoos.
What are your advices, tips, or suggestion for first-time user? thank you!
1 May 2024 5:42pm
You won't get any audio if you don't allow enough time for the hydromoth/audiomoth to write. So when you do a continuous recording you need to experiment a little. I'm sure there is a formula to calculate this, but I haven't figure that out. I typically do 5 min recordings with 10 seconds of write/break time. I think this system is expecting you to subsample, so keep that in mind instead of a continuous recording.
I do 8kHz sampling and get about 7 days of data and then the voltage gets too low and you start getting SD card write errors and missing files.
In terms of analysis, I've had trouble understanding the directionality of the hydromoth and incorporating this into my studies. I always set up two at the same site to check the variability in my call detections and include this into my error analysis.

Attaching a directional microphone to a Wildlife Acoustics ultrasonic recorder?
29 April 2024 4:47pm
30 April 2024 4:28pm
Hi Luke, sounds like an interesting project! One thing to note is the ultrasonic Wildlife Acoustics unit you're looking at is already fairly directional. Take a look at the horizontal directionality plot towards the bottom:
You can see that for the relevant frequencies for slow lorises ultrasonic calls (40-60 kHz), there is 25-30 dB difference between 0 and 180 horizontal degrees. It's not perfect, but is close to some directional mics, and if it works well enough for your project it would save a lot of time and testing!
If you do choose to integrate an external directional microphone, be careful with microphone placement to avoid potential ultrasonic reflections from any hard flat surface like a tree trunk, water surface, or the instrument housing itself. Here's an example of some echo calls from reflective surfaces from bat vocalizations:
It would be helpful to hear how you plan on obtaining behavioral information (and what kind) to correlate with vocalizations? Observations, cameras, biologgers, etc.? This could inform responses a bit more.
30 April 2024 6:19pm
Hi Jesse,
Thank you so much for your reply and for the fantastic knowledge and resources! I was unfamiliar with the plots, so thank you for providing some interpretation- I will have to work to better understanding them. This may change things (I was going off of experience from field work with the last iteration of this WA recorder which had omnidirectional recording) and I may choose to pilot the recorder without an external microphone this summer.
Regarding my plan for collecting behavioral data, I plan to follow 15 wild individuals in a reserve in Thailand (mostly dry evergreen and dry dipterocarp forest with some human modified areas). I intend to use instantaneous focal sampling to observe lorises in two shifts between 18:00-06:00h. During these focal follows I will record all behaviors at 5-min intervals and use all-occurrences sampling for social and feeding behaviors, using an established slow loris ethogram. Simultaneously, I plan to record vocalizations, with the help of a research assistant and field guide. So we will be carrying the recorder with us during behavioral data collection. I intend to match up the timestamped loris vocalizations with the behavioral data to understand the call's function.
30 April 2024 7:00pm
If you have the resources, I would suggest testing the sensitivity and directionality of the system at relevant frequencies both with and without an external mic, and let the results dictate which will be best for your case study.
Another thing to think about since you are manually taking the recordings is if a WA unit is really necessary. You're paying for the technology of a remote system without needing it. Other cheaper handheld recorders (such as Zoom recorders) could free up $$ for a higher quality directional microphone. Although of note is that common Zoom recorders like the H4n only sample up to 96kHz for which the upper frequency limit (48kHz) is getting very close to the frequencies you're likely wanting to measure.

I've a new modular drop-off tag build using @Rob_Appleby's original SensorDrop board that I think would be great for this project too to see if we can drop different compartments, or do various different timed events with the one TimeLord board.
Most importantly, we have to make it play a MIDI version of the DoctorWho theme song when you arm the device. That has to be the #1 feature if you ask me!

Reminds me that we should look at both terrestrial and marine applications when we get stuck in to the demo builds to make sure we cover use cases

Seconded!

Congrats @MattyD797 and team!!! We do a lot of work in the underwater bioacoustic realm and your tool certainly seems like it would be a great instrumental addition to the community. Look forward to learning more about your project!

Yes, I agree with Panji......make sure you have notes of where you put them and remember that photos of trees without leaves look completely different 6 months later......not that I would ever make that mistake.........well not again......especially after spending 2 days trying to find 3 ARU's.

We suggest and use Python Locks for urban areas here in Australia. Can also screw the Mini 2 to a tree or phone post with the python lock.

We've deployed passive acoustic monitors in various urban environments without any issues of theft, even in locations where camera traps and other technology has been historically taken or vandalised. I think acoustic sensors generally look less valuable than other technology, and I would recommend removing or covering any stickers or labels on devices that would otherwise make them more appealing! Placing them in hedgerows or on trees with some (but not too much!) foliage will help keep them well hidden too.

Yep, SD card energy consumption is typically the biggest factor in deployment duration. Some cards, such as large 256GB SanDisk Ultra card will use more than 5 times as much energy as smaller SanDisk Extreme 32GB cards. We've measured a few cards on AudioMoth and generally recommend SanDisk Extreme cards - and the the smaller the better. The Config App does calculations based on the measurements of the SanDisk Extreme 32GB card.
