Homework Help: Physics - Please Help

Posted by Emily on Monday, April 25, 2011 at 3:44pm.

A 60 year old person has a threshold of hearing of 81.0 dB for a sound with frequency f=10,000 Hz. By what factor must the intensity of a sound wave of that frequency, audible to a typical young adult, (sound level=43.0 dB) be increased so that it is heard by the older person.

Thanks for any and all help!
