Answer #1


Transmission coefficient, Itronsmitted lindidend = 0.02 : sound transmission loss, STL = 10 log (4) = 10 log (%0.02) STL = 16

The STL is in dB.

Transmission coefficient, Itronsmitted lindidend = 0.02 : sound transmission loss, STL = 10 log (4) = 10 log (%0.02) STL = 16.99 - flow; given the incidend sound intensity level is to do. 70 = 10 log ( I nedent); Io - 10-12 W/m2 - Incident = 10 - Incident = 10-12 x 107 W/m2 = 10-5 W/m² I transmitted 0.02x Iincident = 0.02 x 10-5 level - = 2 x 10-7 W/m2 This corresponds to sound intensity ß = 10log, (It smitted =10 logo ( 24.02 = ß = 53.01 dB .

    5. The threshold of human hearing at a frequency of 1.0 kHz is usually defined to be exactly 0 dB (for purposes of significant figures, consider this to be an exact, pure number). A research study shows that if exposed to 95 dB of a sound source for a long time, the threshold of hearing will shift upward to 32 dB. This accounts for why it is hard to hear normal conversations for some time after leaving a loud concert....
