Genesis Acoustic Products

Frequently Asked Questions

Doors:

Soundproof doors are available from Genesis Acoustics. We manufacture single & double leaf doors.
The doors can be sold alone or bought as a complete set.
This what is offered with the doors: The doors are made to order, the lead time is about 15 working days.

For those on a tight budget the following guidelines will be useful.

 

 

Windows / Glass:

The most common glass installed in homes & offices is 3mm thick Clearvue which has a poor STC rating of only 23. It is well worth the money spent to replace this with a glass providing better isolation. 10dB represents a doubling or halving of the sound, therefore a benefit of 10 - 15 db as shown below, is a significant improvement.


 

Ceiling Cavity:

Is there a common ceiling cavity over the room/s you want to treat acoustically & the rooms around it? Much sound loss occurs through the ceiling making this an important area to get right. If it isn't treated correctly, sound will travel through the ceiling, into the ceiling cavity & then down into all the rooms sharing the same ceiling cavity. Many jobs are let down by poor or no acoustic insulation in the ceiling cavity. The hardware store grade thermal insulation is NOT intended for acoustic use. If it's pink or green forget it. Acoustic dampening & isolation requires just the right density & mass. Genesis acoustic cavity insulation gives outstanding performance across the frequency range as well as offering excellent thermal insulation. It is available in both rolls & 120 x 60cm panels. One must make sure when doing the installation that no gaps are left between the insulation. It is better that the insulation overlaps by a few centimeters on the edges & rises up against the walls/roofline. If there is sufficient access to the ceiling cavity & it is high enough for workmen to get inside, then the brick wall or dry wall can be raised from ceiling to roof height. The wall should be sealed against the roof line with expanding foam. Decibel Drop soundproofing compound is a valuable tool in treating Rhino board ceilings. It is applied to a second layer of board & then fixed to the ceiling, where the board can be finished as usual.

Drywall Cavity:

The same comments made above for the ceiling cavity apply here too. In addition, it is well advised when looking for maximum privacy or minimum sound transmission loss, to follow the below guidelines:



Questions & Answers:

1) Question:

I have my own artwork to print onto acoustic panels, which formats do you accept?
 

Answer:

We accept the following file formats: .pdf ; .eps ; .cdr ; .ai ; .psd
Please download our artwork specifications (445kb pdf) for more detailed information.

 

2) Question:

How do I acoustically close off a doorway I no longer need, to make it soundproof? E.g. When converting a room into a flatlet.
 

Answer:

Basically you need to build a drywall to close off the doors. The drywall will consist of:
  1. Studs, track & 12,5mm thick Rhino board available from your local timber merchant. Two layers on one side of the drywall & a single layer on the other, it doesn’t matter which side you place the double layer of board.
  2. 50mm thick, Genesis acoustic cavity insulation – noise reduction coefficient 1.0 (100%)
  3. Isolator tape, fixed under the drywall track
  4. Decibel Drop – using this product on one side of your drywall only will double the sound isolation (10db).
  5. Finish by skimming any joints/edges & sand down to ensure a smooth even surface, then prime & paint to finish. You can purchase these items at your local hardware.

This will be the most cost effective manner in which to do your project, with good soundproofing. There are no better options in my opinion.

 

3) Question:

How can I minimize sound travelling out my office to adjacent areas?
 

Answer:

  1. Our acoustic panels are highly efficient (over 90% sound reduction) at absorbing resonance in a room. The greater the surface area of the wall that is covered with acoustic panels, the more sound reflection is dampened. Many standard sizes & finishes are available to achieve the desired result, both in terms of function & the aesthetic. How many panels should be hung will be determined to some degree by other fixtures like doors, windows, cabinets etc. For maxim benefit you should treat the wall from a height of about 80cm from the floor to about a 2m height. This is because this is the area of the wall which is closest to the level of your ear, whether you are in a seated or standing position. Thus acoustic panels hung in this area of the wall will have the greatest influence on the sound that arrives at the ears of those present in the room. The panels can be staggered with spaces in between & do not have to butt up against each other.
     
  2. A common problem in the soundproofing of a room is sound transmission through the door or around the door through the gaps between the door & frame and under the bottom of the door. Our door sealer kit seals all four edges of the door, even the bottom, our acoustic door cover dramatically reduces sound transmission through the door. Also bear in mind, in order of least sound isolation to most are the following door types:
