example 1: a cellist can change the string amplitude between 0.1mm
and 4mm. We can assume that sound pressure is prop.
to string amplitude. What is her dynamic range in dB?
EXAMPLES (similar to homework):
example 2: if a crescendo from f to ff increases the sound level by 6 dB
find the relative sound intensity
find the relative sound pressure
example 3: calculate the sound pressure for a 70dB tone (forte)
(for comparison: normal athmospheric press - 105 N/m2)
example 4: calculate the intensity level in dB when you add sounds
of 65dB and 70dB.
