The dB range with high density and therefore high sound attenuation is particularly recommended in areas where confidentiality is needed such as private offices. With its latest & innovative technology, Armstrong is introducing a new & lower density OP range for optimum sound absorption. OP solutions are designed to fit specific areas such as open spaces or libraries, where concentration is needed.
Our dB range offers excellent sound attenuation and good sound absorption that enhances privacy and confidentiality. Speech privacy is a measure for defining the degree to which conversation cannot be overheard. For good privacy between adjacent spaces, focus on room-to-room sound attenuation and the background noise level.
Standard range provides a unique combination of good sound absorption and sound attenuation that enhance intelligibility for workplace effectiveness. Speech intelligibility addresses the need for comprehension of verbal communication whether naturally spoken or broadcast by an amplified system, within a given space. Intelligibility can be expressed as the difference in decibels between the level of speech and the background noise (signal to noise ratio) as heard at the listener's position. To ensure excellent intelligibility, the difference at the listeners position is recommended to be 10 – 15 dB minimum for people with good hearing and 20 – 30 dB for hearing impaired or users of head-sets.
