The human ear responds more to frequencies between 500 Hz and 8 kHz and is less sensitive to very low-pitch or high-pitch noises. The frequency weightings used in sound level meters are often related to the response of the human ear, to ensure that the meter is measuring pretty much what you actually hear. It is extremely important that sound level measurements are made using the correct frequency weighting - usually A-weighting.
There are two main properties of a regular vibration-the amplitude and the frequency-which affect the way it sounds. Amplitude is the size of the vibration, and this determines how loud the sound is. We have already seen that larger vibrations make a louder sound.Amplitude is important when balancing and controlling the loudness of sounds, such as with the volume control on your CD player.It is also the origin of the word amplifier, a device which increases the amplitude of a waveform. Frequency is the speed of the vibration, and this determines the pitch of the sound.It is only useful or meaningful for musical sounds, where there is a strongly regular waveform.t is also the origin of the word amplifier, a device which increases the amplitude of a waveform.
