What does one dB change in loudness sound like?
examples:
a) calculate the intensity ratio for a 1 dB step.
b) one dynamic step (ppp - pp - p - mf - f - ff - fff) about 6dB
find intensity ratio for each step.
comments on buying audio equipment:
flatness of response, power, freq. rolloff
Adding sounds: DO EXAMPLES ON BLACKBOARD
example: add 440 Hz tones of 60dB and 70dB
demo:
1 dB steps
