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.

Dear Tom, the AudioMoths are being sold via LabMakers (but I do not know if they construct them for them). Have you been in touch with the AudioMoth team? I am sure they will be able to provide you useful feedback regarding what you are trying to do, and LabMakers.
I have only used them to buy things from them.

Accessible acoustic analysis tech for blind scientist - ideas?
31 March 2023 10:52pm
6 April 2023 10:49pm
Hey Kate I don't have any explicit ideas at the moment but will think on it - such a cool concept! I wonder if there's some form of tactile spectrogram that you could develop, or a way that you could have them try to draw a representation (so assign some shape) of what they are hearing as a means of classification a call and then clustering those shapes? There's a way of creating an image using foam and paper I believe so they could have a tactile record of those shapes. Guess it depends what you want to the quantitative results to be. Super cool that you are looking for greater accessibility in acoustics!!!
7 April 2023 1:40am
Hi Kate,
We've developed a screen-reader workflow for a classification problem on our "Ocean Voices" Zooniverse project, which simply asks folks to label sounds based on what they hear and omits the spectrogram altogether. There are lots of screen-reader users who are active in the Zooniverse Talk forums, so they may have valuable input for you as well.
Once a person has labeled data, I wonder if they could run automated detectors over the data in Pamguard, calculate features (using something like the R package PAMpal), and then use the BrailleR package to explore the statistics in R. This article has a pretty interesting summary about statistical software for visually impaired folks - might not be news to your student, but I thought it was pretty cool.
I'm very curious what our friends who are visually impaired might notice in the acoustic data. Best of luck to you and your student!
Cheers,
Anne

Good idea! I've got a ransom assortment of different acoustic recorders I can bring along
5 April 2023 11:58pm
Indeed, I'll be there too! I like to meet new conservation friends with morning runs, so I will likely organize a couple of runs, maybe one right near the conference, and one somewhere in a nearby park where we can look for wildlife. The latter would probably be at an obscenely early hour, so we can drive somewhere, ideally see elk (there are elk within 25 minutes of Portland!), and still get back in time for the morning sessions.
