Five trumpet players have a sound intensity level of 75dB. What would be the sound intensity level of 30 such trumpet players? _______dB
Increasing the sound intensity by a factor of 10 results in an increase in perceived loudness by approx. a factor of 2.
Beta = (10dB)log10(I/I0)
Where I0 = 1.0x10-12 W/m2
