Common Measurements
Acoustics deals with the science of sound, the transmission of vibrations in gasses and solids. Although acoustics implies that you can hear signals, acoustics also deals with signals both below (infrasound) and above the highest frequencies of human hearing (ultrasound). Acoustic measurements can deal with the purely scientific aspects of sound, such as acoustic pressure, energy, or sound power, but you can also use them to evaluate annoyance (in the automotive industry, this is called noise, vibration, and harshness, or NVH), hearing damage potential, or quality of acoustic transducers such as loudspeakers and microphones.
