Answer. Volume or loudness is determined by the amplitude of the sound wave. The pitch of sound of stringed instrument can be varied by varying its length. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves. Amazingly, many musicians, who have been trained are capable of detecting a difference in frequency between two separate sounds that are as little as 2 Hz. If Lo represent the loudness of the faintest audible sound of intensity Io and L is the loudness of an unknown sound of intensity I, then above equation can be written as. Sound level is not a measure of loudness, as loudness is a subjective factor and depends on the characteristics of the ear of the listener. On what factor does loudness of sound depend? Intensity of sound and how it relates to loudness, the decibel levels of different sounds and factors that affect sound intensity. EASY. State True or False. View Answer. Properties of Sound How Does Amplitude Affect Loudness? The 'loudness' of a sound is based upon its intensity, or power per area. ... timbre gives each instrument its own sound when they have _____ pitch and loudness. Energy of a sound source B. C. II. Table 1 gives levels in decibels and intensities in watts per meter squared for some familiar sounds. View Answer. 1. Loudness – amplitude ... Bookmark; 36. That is, the threshold of hearing is 0 decibels. Further,-“the dew factor at night increases the speed of sound as moisture level increases. Pitch A. Loudness of sound is measured in decibel (dB). ... the speed of sound depends on _____ what its traveling through. Long Answer Type Question. So, sound is more clear. Name two factors on which the heat energy liberated a body depend. Name the phenomenon that causes a loud sound when the stem of a vibrating tuning fork is kept pressed on the surface of a table. MEDIUM. ... Name the factor that determines: Loudness of the sound heard. Your teacher will give you a wooden board with two nails in it. Loudness ofsound is not simply the energy reaching the human ear, but it also tells about the sensitivity of human ear detecting this energy. Or loudness of sound is directly proportional to the logarithm of sound. In an attempt to overcome this problem, scales have been developed to correlate loudness with objective measurements of sound. a factor perceived by the ear that depends primarily on the amplitude of the wave the observer hears. The loudness of a sound depends on two factors: the amount of energy it ta kes to ma ke the so und and the distance from the source of the sound. The decibel level of a sound having the threshold intensity of 10 −12 W/m 2 is β = 0 dB, because log 10 1 = 0. Mathematically: L= log⁡I L = K logI -----(1) Where ‘k’ is constant of proportionality. As energy reaching the ear depends on square of amplitude, so loudness of sound depends on two factors (z) Amplitude of sound waves and When looking at a sound wave graph, the higher-pitched sounds feature waves that are closer together, or more tightly wound, while lower-pitched sounds feature waves that are farther apart. Question 25 Suggest three measures to limit noise pollution in your locality. I. Loudness A. The amplitude of the sound wave depends on the vibration caused by the source of the sound. ... the speed of sound depends primarily on the amplitude of the wave observer.
