Effective acoustic insulation for indoor comfort

Rockwool Safe’n’Silent Pro is designed to achieve excellent acoustic insulation performance in all types of drywall partition configurations.

Our lives are very much affected by the increasing level of noise in our environment. As population continues to grow in the recent decades, so has the amount of noise in our surrounding, be it coming from noisy machines.

The policies and guidelines regulating the ambient noise level in our occupied spaces are still at its infancy stage. Hence it is important to address the need for having a comfortable environment in relations to the optimal ambient noise level and then subsequently the most effective way to control it. For one person the sound may be perceived as soothing and comfortable but by another perceived as noise or unwanted sound.

It is difficult to completely eliminate the characteristics of sound like pure tones such as whines and humming or impulsive components such as gun-shot sound or barking dogs that is continually coming on and off. Such undesirable sound interferes with our quality of life during rest and sleep, our ability to converse clearly or even when listening to music or other natural sounds.

Breakthrough technology
Noise Criteria (NC) is one of the important parameters used in measuring the allowable ambient sound level for various types of interior spaces. NC rating is determined through plotting measured ambient noise level spectrum over an NC chart; where NC rating curves is pre-plotted. “By referring to the NC curves, the NC rating is taken at the nearest curve that the plotted ambient noise curve did not cut through. This is the lowest NC rating possible for a particular interior space,” explains Vinay Pratap Singh, Sales Director, Roxul Rockwool Technical Insulation India Pvt Ltd.

Positive impacts
NC ratings are determined by measuring the sound pressure levels across various octave bands, and through comparing it with established NC curves.

The NC was designed to relate human perception of hearing to indoor noise level and thus provide a single value rating for this.

“One major advantage of NC is that it is able to give reference of the resultant ambient noise level of a space or room to ensure occupants are at their intended or desired indoor comfort,” says Singh.

NC comprehensively measures the noise levels of a room, and can encompass more variables such as presence of noise sources like HVAC systems or electrical and lighting ballasts, and resultant effect of interior acoustics (high or low reverberation), and the sound isolation performance of the various materials that are used to enclose the room.

New offering
Roxul Rockwool Technical Insulation India Pvt Ltd has introduced its new offering to the stonewool insulation market as “Rockwool Safe’n’Silent Pro” which is designed and manufactured to achieve excellent acoustic insulation performance in all types of drywall partition configurations. It is recommended to be used for drywall partition applications in hospitals, cinemas, schools, offices, residential and industrial buildings. ‘Safe’n’Silent Pro’ meets the requirements of NC specifications developed by the Rockwool company. NC comprehensively measures the noise levels of a room and with the use of NC ratings, recommends the desired acoustic comfort level of a room or space.

Rockwool Safe’n’Silent Pro is part of the company’s India specific strategy to add value in its offering to the customers in the dry wall partition industry for proper sound insulation, concludes Singh.
