It's a biofeedback problem, right enough, but cogni= tive aspects are important here - there are many people with good hearing t= hat are unaware of their own acoustic output (children, for instance - and = many adults). So, although you might be interested in people with depleted sensory acuity= , who therefore couldn't do what many 'normal' people can do - hear the ref= lected sound of their own footsteps, which ongoing feedback can be used to = calibrate ones sensitivity, useful in stealth situations - the question mig= ht be "can one use any other feedback route in stealth situations?" - could= be a visual metering, for arguments' sake, or haptic input. You're actuall= y interested in a fairly narrow dynamic range, I think, but it's complicate= d by acoustic factors - low-level sounds can carry; for instance, footfalls= on metal floors or some concrete constructions can cause the material to b= ehave as a drum, with resonance over a large volume of material (meaning th= at inverse square law wouldn't apply). So, monitoring for amplitude at the = stealthy subject wouldn't provide good predictions. Also, there's a 'noise floor' aspect to this, and someone with depleted hea= ring might not be fully cognizant of the noise floor? I'll be interested to know what you manage to turn up Cheers ppl Dr. Peter Lennox Senior Lecturer in Perception College of Arts University of Derby, UK e: p.lennox@xxxxxxxx<mailto:p.lennox@xxxxxxxx> t: 01332 593155 https://derby.academia.edu/peterlennox https://www.researchgate.net/profile/Peter_Lennox From: AUDITORY - Research in Auditory Perception [mailto:AUDITORY@xxxxxxxx= ILL.CA] On Behalf Of Blyth M. Sent: 06 June 2016 14:44 To: AUDITORY@xxxxxxxx Subject: Acoustic stealth awareness - hunting for papers Hello list members, My PhD research is investigating auditory fitness for duty in military pers= onnel. Specifically, I am investigating the impact of hearing impairment on= acoustic stealth awareness. This refers to situations where it is importan= t to be quiet to remain undetected by a nearby enemy, and how having a hear= ing loss might affect this ability. As far as I am aware there is limited l= iterature on this type of auditory situation, and wonder if anyone may be a= ble to point me towards relevant papers? I believe a core task involved is the ability to predict the intensity of a= sound at a target's location when you are generating the sound yourself (e= .g. talking, walking on gravel, etc.), therefore allowing you to predict ho= w loud you can be without the target hearing. My literature searches so far= have returned very little, but I wonder if I'm using the wrong terminology= , or missing some old school papers? Any help would be greatly appreciated!
