1.	Which of the following statements is correct?(a) Pitch of the sound increases with increase in frequency(b) Pitch of the sound decreases with increase in frequency(c) Decibel is equal to 1/100 of bel(d) Increase in the amplitude of the sound decreases the intensityThe question was asked in unit test.My enquiry is from Acoustics in portion Acoustics and Ventilation of Construction & Building Materials
Answer» Correct CHOICE is (a) Pitch of the sound increases with increase in frequency Easy explanation: Pitch of the sound increases with an increase in frequency. Decibel is equal to 1/10 of BEL. An increase in the amplitude of the sound increases the INTENSITY.
