That's the question everyone asks when creating an acoustic
At Fibertex Nonwovens, acoustics
has emerged as an important market as the company looks to diversify into new technical areas for nonwovens.
To design their novel acoustic
metamaterial, the team 3D-printed a series of small trimers, arranged and connected in a triangular lattice.
Observation of the architectural structure revealed a considerable influence of the geometrical accordion-like ceiling on subjective perception of the acoustics
, and the results of the measurements of the reverberation time [T.sub.30] parameter.
Applications of this phenomenon in vortex motion have been successfully studied by Smith et al.,  who identified two scattering mechanisms that allow neighbouring modes to interact; scattering occurs at significantly lower frequencies when the mean flow is present; an exchange of energy between mean flow and acoustic
field occurs during scattering.

Previous studies have reported that asymmetric acoustic
design can be tactfully used to achieve noise attenuation.
But appointing an acoustics
specialist can help avoid any audio issues like this."
Buildings benefit from an acoustics
engineer's early involvement.
"The AirHush panel system is a great addition to our full line of acoustical products," says Joerg Hutmacher, CEO at pinta acoustic
. "This system is being offered through a partnership between pinta acoustic
and AirHush ISAT Systems Inc.
