Below the mass-air-mass resonance frequency (about 250 Hz In such a case) the TL of triple glazing is about 3 dB increased, in keeping with the mass law prediction for escalating the window’s mass by fifty%. At bigger frequencies, the TL curves are Nearly equivalent. The STC ratings for The 2 windows are the identical.
At better frequencies, the measured TL drops considerably underneath the mass law prediction. This sharp decrease from the measured TL is usually called the “coincidence dip”.one It can be due to bending waves inside the glass panel. The frequency at which this happens is inversely proportional towards the thickness from the glass. For two mm thick glass, the coincidence dip can be close to five kHz.
Secondary glazing presents the most effective seem insulation. Decreases noise by as many as eighty% and substantially outperforms double glazing.

Higher than the coincidence frequency, laminated glass (consisting of two or maybe more layers of glass bonded with each other by skinny plastic interlayers) can provide A great deal higher TL than stable glass. Laminated glass may well carefully method mass regulation general performance over the coincidence frequency.
Residue: Pick this selection to hear the audio that might be filtered out should you selected "Lower". This is beneficial for locating the ideal options that don't destruction the click here audio.
