Individuals who work in airports, factories, and on construction sites are accustomed to wearing hearing protection, but most of us are exposed to dangerous noise levels nearly everywhere we go! The typical city dweller or suburbanite is routinely exposed to noise levels of 50 to 70 decibels (dBA), and levels can reach 110 dBA near construction zones, airports, and highways. Excessive workplace noise has a detrimental effect on worker productivity and accuracy, and sustained exposure to 85 dBA or higher can cause permanent hearing loss.

Most of us have learned to tune out excess noise in familiar areas, but that doesn’t mean that we should! National Custom Hollow Metal proudly offers custom-built Sound Safe Sound Transmission Control (STC) doors & frames that feature superior noise reduction capabilities. Sound Safe doors are ideal when you need a few sound-rated openings quickly, and we offer the fastest production cycle in the marketplace.

Sound Safe doors & frames are ideal for recording studios and auditoriums, and they’re also an excellent option for boardrooms or meeting spaces where confidential information is routinely discussed. STC ratings measure a door or building partition’s ability to attenuate airborne sound, and range from 20 to 60. A rating of 20 offers average noise suppression, and soundproofing for recording studios typically requires an STC rating of at least 45. Our SoundSafe Doors have an STC rating of 51, which renders voices on the other side of the door almost completely inaudible.

We can manufacture STC doors & frames as a complete installation-ready assembly in any size up to 4’ x 8’, and they can be configured as a single or pair entry. Your order will include free Quik Ship service, with lead times of approximately three weeks. And if that’s not fast enough, we also offer expedited shipping time tables of 5-10 days for limited-quantity orders. Just let us know when you need your doors shipped, and we’ll take care of the rest. The Difference is Quality at NCHM, and you can always order with confidence because we stand behind all our products with a one-year warranty!
