Sound passes through the air. This is in effect a simple property of physics which has been recognized for many years and which must
be applied to the construction of common walls. It is not rare to see some common walls in the workplace, perforated by several openings to permit the
installation of electrical outlets for telephones or cables. But, as the graphical illustrations demonstrate, even these small holes can allow enormous amounts of noise to pass through.Insonorisation GLH Inc.
has therefore developed a new electrical box which is completely sealed – airtight – and which therefore permits no noise to escape. This new ingenious conception stops all acoustic escape within the interior of common
walls. |
