Dear Richard and Ty

Thanks very much for your messages! I do want to record the actual noises not just sound level, because we will then use Avisoft software to analyse the spectrograph of sounds to try and ID different sounds such as bird song, traffic, to understand the noise environment and correlate different types of noise (or spectrograph patterns) with the participants physiological state. One final question! would the Tiny electret condenser microphone capsules or micro-electro-mechanical systems allow me to do that because they are clearly substantially cheaper than the microphone systems? I guess the other relevant thing to point out is that I will also get video data with a head cam and light data, so will need to synchronise all systems together. Thanks everyone, this is incredibly helpful! Best Wishes, Susannah

Thanks so much, Peter. Thats really useful. I guess in my naivety I have assumed that if the microphone is positioned next to the ear, then it will pick up what the ear hears, but maybe that’s not the case! I did find this one Sonic Studio’s DSM-6S/L: https://www.sonicstudios.com/dsm.htm#chart, which seems designed for ambient noise, but I have never tried it. Does anyone have experience of it? Thanks very much, Susannah
