Thanks for a comprehensive overview. You noted Whisper at 1metre= 30 DB and spoken at 1 meter is 60-70 dB. How do these values change at 30 cm?

Thanks for the question. Free field testing is quite a course assessment of hearing as the exact distance between tester and patient along with amplitude of speech/ whisper being quite variable between testers. In general - Loud speech at 60-100cm ~ 70dB Conversation at 15-30 cm ~ 60 dB Conversation at 60-100 cm ~ 50 dB Whisper at 15-30 cm ~ 30 dB Whisper at 60-100 cm ~ 10 dB In practice though, its main use is to screen for grossly normal/ abnormal hearing, but less helpful to approximate thresholds
