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.
What else can I help you with?
Is the frequency determined by it loudness or not?
No, the frequency of a sound wave is determined by its pitch, while the loudness is determined by the amplitude of the wave. Frequency refers to how high or low a sound is perceived, while loudness refers to the intensity or volume of the sound.
How is loudness of sound determined?
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.
What is loudness of sound determined by?
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).
The loudness of a sound wave is determined by its?
By its amplitude. Really loudness is sound intensity & intensity depends on square of amplitude ie. higher the amplitude higher the intensity which means higher the loudness.
Which wave property determines a)loudness b)pitch?
a) Loudness is determined by the amplitude of a wave, which corresponds to the intensity or volume of sound. b) Pitch is determined by the frequency of a wave, which corresponds to how high or low a sound is perceived.
Is the frequency determined by it loudness or not?
No, the frequency of a sound wave is determined by its pitch, while the loudness is determined by the amplitude of the wave. Frequency refers to how high or low a sound is perceived, while loudness refers to the intensity or volume of the sound.

The loudness of a sound wave is determined by its?
By its amplitude. Really loudness is sound intensity & intensity depends on square of amplitude ie. higher the amplitude higher the intensity which means higher the loudness.
Is it true that loudness is determined by how often the particles in an object vibrate when a wave passes through an object?
No. Loudness is not determined by the wave's frequency, but by its amplitude. That's how much the particles of the object move (how large is the displacement).
Which wave property determines a)loudness b)pitch?
a) Loudness is determined by the amplitude of a wave, which corresponds to the intensity or volume of sound. b) Pitch is determined by the frequency of a wave, which corresponds to how high or low a sound is perceived.
What is loudness of wave?
Loudness is a subjective perception of sound intensity by an individual. It describes how loud or soft a sound is perceived by the human ear. The loudness of a wave is determined by its amplitude, with larger amplitudes corresponding to louder sounds.
How loud a sound seems is determined by what measurement of the sound waves?
Loudness is determined by the amplitude of the sound waves.
How can the loudness of a sound be determined by the waves?
The loudness of a sound (or intensity) corresponds to the sound wave's amplitude. The amplitude of a wave is the distance from the midpoint of the wave to a high-point (crest) or low-point (trough).
How does amplitude affect the loudness of a sound?
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
What does Loudness and pitch do?
Loudness refers to the perceived intensity or volume of a sound, while pitch relates to the perceived highness or lowness of a sound. Loudness is determined by the amplitude of the sound wave, while pitch is determined by the frequency of the sound wave. A higher amplitude results in a louder sound, while a higher frequency results in a higher pitch.
Are loudness and pitch properties of sound or property of waves?
Loudness and pitch are properties of sound which can be determined by looking at the sound wave. You have a high pitch when the frequency of the wave increases or the wavelenght (lambda) decreases. When the amplitude increases the loudness of the wave increases as well.
