The loudness of a sound is represented by the amplitude of the wave displayed on an oscilloscope. Higher amplitudes indicate louder sounds, while lower amplitudes indicate quieter sounds. The vertical axis of the oscilloscope shows the amplitude of the sound wave.
In order to find out the loudness of sound waves, an oscilloscope can be used. Oscilloscopes demonstrate sound wave patterns, but it must be hooked up to a microphone in order for it to be heard.ADDED: It is measured directly and quite accurately by sound-level meters, and these are used by environmental-monitoring specialists etc..You can use an oscilloscope, but not directly. That shows the sound's wave-shape as a voltage analogue, so to calculate the sound level itself from the display on the screen, you also need to know the sensitivity of the microphone and the gain of any amplifier. If you want to determine the sound's full characteristics, replace the oscilloscope by a spectrum-analyser.
Loudness is the property of sound that describes our awareness of the energy of a sound. It is subjective and depends on the amplitude of the sound wave.
The loudness of sound is determined by the amplitude of the sound wave. A larger amplitude produces a louder sound. Decibels (dB) are used to measure loudness on a logarithmic scale.
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
Loudness is to brightness as sound is to light.

The amplitude determines the loudness of a sound wave.
The amplitude of sound waves is what humans perceive as loudness.

Loudness is to brightness as sound is to light.
The loudness of a sound depends on the amplitude of the sound wave. A higher amplitude corresponds to a louder sound. The human perception of loudness also depends on the frequency of the sound wave and the sensitivity of the human ear.
Yes the loudness of a sound is called its intensity.
The unit of sound loudness is the decibel (dB). It is a logarithmic scale that measures the intensity or volume of sound.
The amplitude of a waveform describes a sound's loudness. The greater the amplitude, the louder the sound.
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
