# What does acoustic reactance mean?

## Here's a list of possible definitions for the term acoustic reactance:

### Princeton's WordNet

1. acoustic resistance, acoustic impedance, acoustic reactance(noun)

opposition to the flow of sound through a surface; acoustic resistance is the real component of acoustic impedance and acoustic reactance is the imaginary component

### Wikipedia

1. acoustic reactance

Acoustic impedance and specific acoustic impedance are measures of the opposition that a system presents to the acoustic flow resulting from an acoustic pressure applied to the system. The SI unit of acoustic impedance is the pascal-second per cubic metre (Pa·s/m3), or in the MKS system the rayl per square metre (rayl/m2), while that of specific acoustic impedance is the pascal-second per metre (Pa·s/m), or in the MKS system the rayl. There is a close analogy with electrical impedance, which measures the opposition that a system presents to the electric current resulting from a voltage applied to the system.

1. acoustic reactance

Acoustic reactance is a property of an acoustic system that measures the opposition to the change of acoustic flow rate through the system due to its inertia or elasticity. It is a kind of acoustic resistance that reacts to changes in sound pressure and air flow, and can affect the transmission and resonance of sound waves.
