An oscilloscope measures electrical signal amplitude and wavelength.
A decibel or sound-level meter. A cheap one is available at your local Walmart for about $20 located in the car audio section. If not instore, online. They make much better ones, but if you are looking to just get a rough idea, this is the way to go.
loudness of sound is subjective quantity and depends upon the sensitivity of the person hearing the sound whereas intensity of sound is a physical quantity and can be measured accurately.
Sound intensity is measureable by the compression of air wrought by the soundwave. Use a "sound pressure level meter", available from most hardware stores, to measure the intensity of sound.
Your ears and the sound pressure level meter measure the sound pressure of a sound wave.
Note: Sound power (sound intensity) is the cause -
and the sound pressure is the effect.
The effect is of particular interest to the sound engineer.
Wellknown is a sound pressure level meter = SPL meter. Our ear drums are moved by sound pressure variations and so are microphone diaphragms. Forget the intensity!

There is not only "one" amplitude.
There is an amplitude of particle displacement ξ, or displacement amplitude,
an amplitude of sound pressure p or pressure amplitude,
an amplitude of sound particle velocity v, or particle velocity amplitude,
an amplitude of pressure gradient Δ p, or pressure gradient amplitude.
If the "sound" inceases, the "amplitude" also increases.
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.Amplitude measure how forceful the wave is,It is measured in decibels or dBA.
There are various instruments that are used to measure the sound waves. Some of these instruments are the Decibilometer, Oscilloscope and the Sound Level Meter.
A sound level meter measures the loudness of sound.
A dosimeter measures how much sound a person is exposed to.
Take your pick.

echo is used to measure the velocity of sound
The amplitude of sound is measured in N per square meter ( N / m^2 ) or in Pascals ,since
1.0 Pa = 1.0 N/m^2.
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.

Sound intensity decreases when amplification (volume) decreases.
Sound intensity or acoustic intensity is defined as the sound per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
Sound intensity (I) is a sound energy quantity in oposite to sound pressure (p), which is a sound field quantity. I = p². Sound intensity or acoustic intensity I is defined as the sound power Pac per unit area A. That is: I = Pac / A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
A uterine sound measures uterine depth.
Yes. A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data. A photometer is a light sensitive device and measure the power of light.
A seismograph records the intensity measured by the Ritcher Scale.

A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
instrument for measuring sound was named after which scientist?
A seismograph is an instrument that measures the intensity of earthquakes. Seismograph technology would refer to the science involved with the design or improvement of the instrument.
Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
Most famous is a SPL meter (Sound Pressure Level).
The instruments are variously known as sound level meters, noise meters, noise dosimeters, acoustic transducers, etc.
