The frequency of a sound is the number of cycles of a sound wave in one second. You say that machinery makes a noise. There are two main properties of a regular vibration - the amplitude and the frequency - which affect the way it sounds. The time period is the time required for the wave to complete one cycle. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear. The physical concept of sound includes both audible and inaudible sound. Is it good as it sounds? A sound spectrum displays the different frequencies present in a sound. Sound Absorption: (1) The process of dissipating sound energy. Suppose a sound wave is producing total 5 complete vibrations in a second. Sound: Sound is vibrational disturbance, exciting hearing mechanisms, transmitted in a predictable manner determined by the medium through which it propagates. In the word `pneumonia', the letter p is not sounded. This theory of how we hear sounds states that there are pulses that travel up the auditory nerve, carrying the information about sound to the brain for processing, and that the rate of this pulse matched the frequency of whatever tone you are hearing exactly. the measurement of the duration of and intervals between sounds.
