Detailed explanation-1: -Pitch of sound is determined by its frequency. Two notes of the same amplitude and sounded on the same instrument will differ in pitch when their vibrations are of different frequencies.
Detailed explanation-2: -The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
Detailed explanation-3: -The pitch of a sound is related to frequency, which is related to the wavelength of a wave. The higher the frequency (shorter wavelength), the higher the pitch. The loudness of a sound wave is related to the amplitude. A bigger amplitude results in a louder sound.
Detailed explanation-4: -The number of vibrations per second or frequency determines the pitch of a sound. Frequency is directly proportional to pitch. Higher the frequency, higher the pitch.
Detailed explanation-5: -The amount of energy required for the source to generate sound. The properties of the media in which the wave is travelling. The source’s and the environment’s frequency responses.
