SOUND TRANSMISSION CLASS RATINGS FOR CONCRETE MASONRY

DETERMINING SOUND TRANSMISSION CLASS (STC) FOR CONCRETE MASONRY. Sound transmission class (STC) provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications.The STC of a wall is determined by comparing sound transmission loss (STL) values at various frequencies to a standard contour.STL is the decrease or attenuation in sound

Sound Absorption Performance of Highly Porous Stainless

 · The sound absorption performance was investigated at 200–6300 Hz for this foam and at 2500–4000 Hz for its composite structures. The results show the whole absorption performance of the sample can be significantly improved by introducing an air gap and further improved with introduction of both the gap and a perforated plate.

Primary investigation on sound absorption performance of

This titanium foam showed a good performance of sound absorption and its sound absorption coefficient could be more than 0.6 in the sound-wave frequency range of 3150–6300 Hz and even exceed 0.9 at the resonance frequency.

MAR13300 Acoustic Design Guide v2Bradford Insulation

 · In sound absorption applications the NRC is often used as a performance measure. The higher the NRC the greater the sound absorption at those frequencies. However NRC does not rate sound absorption at frequencies less than 250 Hz. Absorption at the low frequency is often the most critical in building

Reducing Noise In Residential Spaces

 · A hard surfaced floor be it tile hardwood or ceramic is not only going to reflect any sound generated within the space but will also magnify the sounds generated by the floor such as footfall or the scuffling of furniture. If the space is voluminous in nature due to high ceilings the sounds are going to be even louder and more intrusive.

Sound absorption characteristics of a high-temperature

Abstract This article is dedicated to sound absorption properties of porous zeolite with macropores a ceramic material fabricated by high-temperature sintering. Acoustical properties of this ceramic material are studied by two analytical models Delany–Bazley model and Johnson–Allard model where the latter one shows a better fit to the experimental results.

Aluminium Foam Properties and applications Materials Hub

Aluminium Foam is extremely strong and can absorb a great deal of mechanical energy when deformed making it an attractive material for impact energy absorbers. Unlike polymeric foams which tend to spring back Aluminium foams do not do this preventing any secondary damage. There is a direct relationship between the density and strength of the
