i have been really into their work for the past year, highly recommend their book (called aural diversity) but here i'm linking a great talk by Drever that you might enjoy whether you're into acoustics or entirely new to it (lots of talk about hand dryers/bathroom noise)... both professors / composers are doing amazing work in audiology, sound art, soundscape studies, music, urban design, etc... since i started having hearing issues and became more interested in studying sound (informally), especially in the context of urban planning, their work has become really important to me and i think some of you would also find this interesting :)
