[ə′küs·tik ‚rē·flek′tiv·əd·ē]
(acoustics)
Ratio of the rate of flow of sound energy reflected from a surface, on the side of incidence, to the incident rate of flow. Also known as acoustic reflection coefficient; sound reflection coefficient.

The study shows that these barriers are of very high acoustic reflectivity (95% and above) (Bulletin of the Acoustical and Insulation Materials Association, 1974) and of low sound absorption for the frequency band of highway noise between 250 Hertz and 4000 Hertz.
The pores, created by using stones of similar size in the asphalt mix, are thought to dampen the hiss of the pumped air and to impair the acoustic reflectivity of the road surface.
