Subject: hearing aid question: "boominess" From: "Richard H." <auditory(at)AUGMENTICS.COM> Date: Mon, 2 May 2005 17:03:18 +0100Hi team, I am a newly qualified dispenser and need a bit of advice please. I am dispensing a digital hearing aid and the patient reports an unpleasant "echo" or "boominess". This is NOT occlusion. After a lot of trials I can make the boominess go away by dropping gain in a notch around 1kHz. However this also reduces speech volume & intelligibility! The loss is 40dB flattish, and I am using WDRC with 55-60dB TK point. This is driving me nuts ... is there anything obvious I should be looking at for causes of "boominess"? Thnaks! regards, Richard -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.308 / Virus Database: 266.11.1 - Release Date: 02/05/2005
