Answer. (a) The loudness of a sound wave is determined by the amplitude of the wave.The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater.Intensity determines loudness of a sound so the greater the intensity, the greater the loudness. Intensity is found by using the equation power/area.

What determines the loudness?
The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater.
What determines loudness quizlet?
Intensity determines loudness of a sound so the greater the intensity, the greater the loudness. Intensity is found by using the equation power/area.

Images related to the topic1. Which wave property determines (a) Loudness (b) Pitch?
Which of the following is associated with loudness?
The loudness of a given sound is closely associated with the amplitude of the sound wave.
Does frequency determine loudness of sound?
You might suspect, that the higher the frequency, the louder we perceive a noise, but frequency does not tell us how loud a sound is. Intensity or loudness is the amount of energy of a vibration and is measured in decibels (dB). If a sound is loud, it has a high intensity.
What part of the wave determines the loudness?
The amplitude of a sound wave determines it relative loudness. In music, the loudness of a note is called its dynamic level.
Which scale is used for loudness of sound?
Sound power is usually expressed using the logarithmic decibel (dB) scale chosen to accommodate human loudness perception. Increasing sound intensity by 10 dB is perceived as an approximate doubling in loudness but represents a tenfold increase in sound power.
What determines loudness and pitch?
The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.

SOLUTION · Sound is a wave and a high amplitude wave carries a large amount of energy. · The loudness of a sound wave is directly proportional to the square of …
How does amplitude determine loudness quizlet?
Volume is determined by the amplitude of a sound wave. Loud noises have bigger amplitudes (taller sound waves). Soft noises have smaller amplitudes (shorter sound waves).
What determines the pitch and loudness of sound quizlet?
What determines sound volume? Sound volume is determined by the amplitude of a sound wave. What determines sound pitch? Sound pitch is determined by the frequency of the sound wave.
What is loudness music?
In acoustics, loudness is the subjective perception of sound pressure. More formally, it is defined as, “That attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud”.

What does loudness mean?
Definition of loudness
: the attribute of a sound that determines the magnitude of the auditory sensation produced and that primarily depends on the amplitude of the sound wave involved.
What determines the loudness of sound Class 8?
The amplitude of sound determines the loudness of sound.
What property describe the loudness of the sound?
The decibel (dB) is the unit of measure that describes the intensity or loudness of sound. Decibel levels of common sounds are shown in the figure below. Sounds depend on the properties of the sound waves that enter your ear. Loudness or softness depends on the wave’s amplitude.
What is amplitude in sound?
Amplitude is the relative strength of sound waves (transmitted vibrations), which we perceive as loudness or volume. Amplitude is measured in decibels (dB), which refer to the sound pressure level or intensity. The lower threshold of human hearing is 0 dB at 1kHz.
Which property of a wave makes it the loudest?
The correct answer is Amplitude. It is the energy of a sound wave. The amplitude of a sound wave depends on the energy by which an object vibrates. The amplitude of the loud sound is high and the amplitude of the soft sound is low.
What is loudness unit?
sone, unit of loudness. Loudness is a subjective characteristic of a sound (as opposed to the sound-pressure level in decibels, which is objective and directly measurable).
What is amplitude and loudness?
1. Amplitude is the maximum displacement of the vibrating body on one side. 2. Loudness of sound is proportional to the square of the amplitude of the vibration producing the sound.
What scale is used for loudness of sound or music Brainly?
The scale for measuring intensity is the decibel scale. The threshold of hearing is assigned a sound level of 0 decibels (abbreviated 0 dB); this sound corresponds to an intensity of 1*10–12 W/m2.
What is loudness quizlet?
Loudness. amplitude and the intensity of sound. The relationship is measured by dBSPL. Sound intensity is physical and amplitude is perceptual.

Is amplitude pitch or loudness?
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.
What is loudness of sound class 9?
Loudness: Loudness is the response of ear to the sound. Loudness is proportional to the square of the amplitude of the vibration body producing sound. The more the amplitude of vibration, the sound is the loud. The lesser the amplitude of vibration, the sound is feeble.
