absorption coefficient
absorption coefficient
(OP)
while studying vibrations I constantly came across 2terms: transmissionloss factor and absorption coefficient.
Where excatly is the difference? Can one generaly say, that the transmissionlossfactor is for menachnical vibrations, whereas the other one is for acoustical purpose?
Thanks,
Aoife

RE: absorption coefficient
E=Er+Ea+El
for transmission loss, is E-El.
for aborption coefficient, is Ea/E.

Just as the two types of materials are fundamentally different, so are these tests.
RE: absorption coefficient
When I lived in a 1960s side-by-side duplex apartment our neighbor had a teenaged daughter, and my outspoken wife is from the Bronx, New York . I bet we all were glad the "common" wall had a relatively high transmission loss, and it was sealed at the edges, so there were no flanking paths for sound to sabotage its performance.
