Reverberation in acoustics is when a sound is reflected causing more noise until it is absorbed. If reverb takes to long from when the initial sound reaches the person it is normally unwanted noise.

In some places such as concert halls a certain amount of reverberation is wanted but there is a need to control it.

It can be controlled by installing sound barriers, ceiling baffles and banners or decorative acoustic wall panels to name a few items. These items can absorb the sounds reducing the reverb.
In a follow up to the HYENA study in 2004–2006 researchers sought to evaluate the association of exposure to aircraft and road traffic noise with the incidence of hypertension and other cardiovascular outcomes. Their conclusion was: [...]
