隔音夹胶玻璃

Modern building designs emphasize liberal use of glass. However, sound transmission can be significant through ordinary glass. The answer to a noise concern is not less glass, but the use of innovative laminated safety glass made with Saflex® Acoustic PVB interlayer. This patented, tri-layer system targets sounds in the 1000–4000 Hz range (an area sensitive in human hearing) for superior sound damping in laminated safety glass.

Saflex® Acoustic PVB interlayer

Innovative acoustic interlayer for laminated glass

Modern building designs emphasize liberal use of glass. However, sound transmission can be significant through ordinary glass. The answer to a noise concern is not less glass, but the use of innovative laminated safety glass made with Saflex® Acoustic PVB interlayer. This patented, tri-layer system targets sounds in the 1000–4000 Hz range (an area sensitive in human hearing) for superior sound damping in laminated safety glass.

Sound transmission loss
Sound transmission loss

*Sound Transmission Loss of Laminated Glass with Saflex® Acoustic interlayer and Saflex® Clear interlayer. Configuration = 44.2 The ability to reduce noise as perceived by the human ear can be measured. This measurement involves sending specific frequencies of sound through a material, in this case, laminated glass with Saflex® Acoustic interlayer, and remeasuring what comes “through” the glass to determine what gets “filtered” out. The transmission loss is recorded and can be illustrated in graphical form as shown above in the figure.

As a result of Saflex Acoustic PVB interlayer availability, architects and engineers can design elegant spaces that reduce perceived loudness by up to 50%—decreasing transmitted sound up to 10 decibels versus non-laminated glass, in the critical frequency range.

Saflex Acoustic PVB interlayer is also compatible with the Vanceva® Colors and Earth Tones interlayer systems, so architects and designers can create safe spaces without sacrificing style or comfort.

Applications:

Airports, hotels, business offices, government buildings, hotels, restaurants, boardrooms, meeting rooms, medical care centers, health clinics, school classrooms, lecture halls, recording studios, broadcast facilities, concert halls, theaters, auditoriums, museums

Noise control

What are the effects of noise on health?

The World Health Organisation(WHO) recommends an ambient noise level of below 35dB for a good night's sleep. The acoustic danger threshld has been set at 90 dB. In excess of 105 dB, irreparable hearing loss may occur. The threshold of acoustic pain has been set at 120 dB. Above this, noise becomes unbearable, leading to extreme pain and hearing loss. Noise is blame for:
-11% of accidents in the workplace;
-15% of lost working days;
-20% of psychiatric hospitalisation admissions.

How to improve the acoustic performance of glazing?

The acoustic performance of glazing was improved mainly by increasing the thickness and asymmetry of glass panes in double-glazed units. In certain cases laminated safety glass would behave almost like monolithic glass of the same thickness. On average it is possible to improve performance by 1 to 3 dB compared to glass similar in type or thickness and above all to ensure uniform performance across a broader range of frequencies.

Will using an acoustic glass stop all noise from entering my house?

No, it will however reduce the amount of noise that both enters and leaves your home by approximately 3-4dB over standard double-glazing, which is an audible difference. The noise reduction gained will be dependent upon the quality of your window frames and the type and level of noise you are trying to cut out.
