Unique Amplitude Of Sound
In this lesson we will learn about the amplitude of sound and how to protect our ears from very loud sounds.
Amplitude of sound. In this equation ρ is the density of the material in which the sound wave travels in units of kgm 3 and vw is the speed of sound in the medium in units of ms. The strength or level of sound pressure. The one with the higher amplitude has the louder sound.
Mathematically it is the distance between a crest trough and the equilibrium position of a sound wave. Two graphs showing the difference between sound waves with high and low amplitude e. The amplitude of sound changes suddenly in case of a so.
The sound is loud and has a high pitch if the frequency of vibration is higher. There are two properties of a vibration which is regular and the frequency and the amplitude which affect the way it sounds. Please scroll down to see the correct answer and solution guide.
The Amplitude is the vibration of size and this determines how loud the sound is. Amplitude measures how forceful the wave is. 6 lessons in Sound.
The Pitch of the sound depends on the frequency of vibration of the waves. If a sound is described to have a lower pitch it means that it vibrates at a lower frequency. Soft sound like musical sound.
The amplitude of a sound wave determines its relative loudness. In working with sound it is essential to have a firm grasp of amplitude and loudness and the various methods of measurement. Sound energy travels in waves and is measured in frequency and amplitude.
