During the frigid winter months, we may hear from customers that their Green Glue product has frozen. Feezing can occur for many reasons, but the primary one is when the product is left outside, in a cold non-insulated environment, or during transport in the middle of winter. We advise customers not to panic as Saint Gobain altered the formula to compensate for this issue. Some key points to consider regarding the Green Glue Noiseproofing Compound, the freezing issue, [...]
One of the more frequently asked questions we receive is "Does your Acoustic Tiles solve impact noise?". The short answer is: no. Let's look further into the reasons why that is the case. What is impact noise? Impact sound, (or impact noise), is a form of structure-borne sound that occurs when an object impacts on another, resulting in the generation and transmission of sound. The structural vibration caused by the impact results in the sound [...]
Sound Part five: Our fifth acoustic technical note will discuss noise control techniques at the source, the transmission path, and protective measures at the receiver. In general, noise control measures can be classified into three categories. Noise Control at the source Noise control in the transmission path Use of protective measure against noise in the receiver The method or combination depends on the magnitude of the required noise reduction and the economic and operational considerations. [...]
Sound Part Three: The third part of our acoustical technical notes will discuss frequency weightings and octave bands. Frequency Weightings: Frequency weightings also known as frequency networks and frequency filters, correlate measured sound levels with the subjective human response. The human ear is frequency selective, between 500 Hz and 6 kHz, our ears are very sensitive compared with lower and higher frequencies. The frequency weightings used in sound level meters are often related to the [...]
Sound Part Two: This second part of the acoustical technical notes will allow us to expand your knowledge about sound. Part two discusses levels, decibels, and intensity of sound. Every day, we experience sounds in our environment, such as the sounds from television and radio, household appliances, and traffic. Normally these sounds are at safe levels that don’t damage our hearing, but sounds can be harmful when they are too loud. Decibels: The effects of [...]
