AIHA, in a letter to Jordan Barab of OSHA, strongly encouraged OSHA to consider reducing the 8-hour TWA for noise from 90 dBA to 85 dBA and a 3 decibel exchange rate. A copy of the letter, dated April 28, 2009, can be found HERE. The letter is very similar to one AIHA submitted to Edwin Foulke of OSHA in March of 2007. A copy of this letter can be found HERE.
Is a reduction in the noise PEL on the horizon?
