This answer is only brief.
An Impedance Tube is one way of measuring the sound absorption of a material. This apparatus is a metal tube of a few inches in diameter and about 5 feet or so in length. The sample material is secured at one end, and a loudspeaker at the other end. The magnitude of the sound standing waves is measured along the centre of the tube, by a travelling microphone. From this is calculated the sound absorption.
The Reverberant Room method. In a large ( a few hundred cu m volume), room constructed with hard reflective walls, the Reverberation Time is measured at many frequencies and positions in the room. This gives a number called T60, and is the time a sound takes to decay by 60 dB. (decibels) This measurement is repeated both with and without the sound absorbent material in position. Usually a sample size of 10 m2 or so is needed. Rather special rooms are needed to give reproducible results.
From these measurements, the sound absorption is computed.

What Equipment used to measure the temperature of an object.?
Pyrometer
Why is an oscilloscope used to measure sound waves?
An oscilloscope is used to measure sound waves because it can visually represent the waveforms of sound signals in real-time. This allows for precise measurements of characteristics such as frequency, amplitude, and waveform shape, which are essential in analyzing and troubleshooting audio systems and equipment. Additionally, an oscilloscope can provide a visual representation that helps in identifying distortions or anomalies in the sound wave.
What equipment do you used to measure sound?
Sound is commonly measured using a sound level meter which detects and measures sound pressure levels in decibels (dB). This device typically includes a microphone, amplifier, and digital display. Sound level meters can be handheld or installed permanently for continuous monitoring in various environments.
What is used to measure theamplitude or the loudness of sound?
You can measure the sound pressure with a sound pressure level (SPL) meter. Loudness ist a psycho acoustical sensation.
What is the equipment used to measure magnetic force called?
The equipment used to measure magnetic force is called a magnetometer. Magnetometers can come in various types, such as fluxgate, Hall effect, or SQUID magnetometers, and are used to detect and measure magnetic fields.
What tools are used to measure sound?
Tools used to measure sound include sound level meters, which measure the intensity of sound in decibels, and spectrum analyzers, which show the frequency components of sound. Other tools include acoustic calibrators for calibrating the measurement equipment and noise dosimeters for monitoring sound exposure over time.

protractor
What ports are used to connect external sound equipment?
The ports used to connect external sound equipment are Line In, Mic and Line Out. These ports are usually located on the computer's sound card.
What are the standard units used to measure sound power?
The standard unit used to measure sound power is the decibel (dB).
What are the units used to measure sound pressure levels?
The units used to measure sound pressure levels are decibels (dB).
How can you measure sound in an experiment?
Sound can be measured in an experiment using a sound level meter, which detects and quantifies sound pressure levels in decibels (dB). The meter records the intensity of sound waves in relation to a reference value, providing an objective measure of sound levels in a given environment. Additionally, specialized equipment such as microphones can be used to capture and analyze sound waves across different frequencies and amplitudes.
Which piece of equipment is used to measure mass?
A Scale.
What is the equipment used to measure colour?
You use a spectrophotometer.
