Does anyone know how loud a sound needs to be to *wake up* the intended recipient (the sort of "smoke detector in the middle of the night" scenario)? Clearly it will depend on (at least) (1) the nature of the sound -- pitch, frequency components, temporal properties, speech/nonspeech; (2) the intervening environment -- the distance to the user, walls, background noise... Also, any info on the duration required at that dB level? Particularly effective temporal patterns or pitch ranges? By the way, I already have plenty of information on auditory warnings for awake listeners (e.g., Patterson). Any comments and references would be much appreciated - I will compile responses and post to the list.
