Question 4
Maximum variation of an acoustic variable is 0.4 mm. Minimum variation is 0.2 mm. Find the amplitude.
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean

Question 5
The maximum variation of a wave is 764 and the mean is 521. What is the minimum variation?
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean
P µ A2 A = Max – Mean I = Power / beam area
Mean = (Maximum + Minimum)/2 Mean = Min + Amp
Mean = max – amp Min = Mean – Amp
Max = Amp + Mean
