Question 2 The sound pressure of a sports car's engine is 10000 times than that of a sedan, how many dB more is the sports car's sound pressure? dB A cat can detect 1000 times more sound power at 30,000 Hz than a human. How many dB is this increase? dB Sally requires 10 times more sound pressure to detect a 1000-Hz tone than Mary. How many dB less sensitive is Sally? dB Many animals can detect an intensity that is 4 times more than the minimum sound intensity. How many dB is this? (please round to two decimal values). dB When the distance from the source is increased from 2 m to 4 m, by what factor does the sound intensity decrease? By how many dB does the sound intensity decrease (please round to two decimal numbers)? dB
