Are you worried that your neighbors may complain about sound systems and high sound level of your new house? Well, forget it and be a party freak and get yourself moving to beats of music systems just by getting your new house sound insulated. Your house needs sound testing, which may be separated by equal or different distances from your neighbors. You just need to get an expert solution about sound insulation testing in order to get your house sound proof.
What is sound insulation testing?
In simple words sound insulation testing can be defined as minimum separations between the walls, which is required between walls & floors to meet the requirements as stated by Approved Document E generally termed as ADE by UK government. These tests are carried out to ensure that your building construction demonstrates an acceptable level of airborne and impact sound insulation performance. Pre assessment of construction is done and results are provided for desired construction.
Understanding airborne sound and impact
Airborne sound is a sound that is transmitted through air. This sound may be unacceptable in the nearby locality. Hence there must be well maintained distance between you and your neighborhood, according to ADE rules and regulation. Well, what is impact, then? Have you ever heard or felt the vibration of DJ and other song. These sounds tend to vibrate the walls of your house this is called impact of sound. Your construction must be in accordance with ADE rules for acceptable sound in the neighborhood.
What is Acoustic test and How to do it?
A poor quality construction and workmanship may cause airborne sound travel directly in between door gaps and windows which may result in flanking sound to the outer environment. Though the element itself provides insulation but still then a small sound from gaps may cause an increase in transmission of airborne sound.
The amount of airborne sound can be reduced by using acoustic absorption. This reduces the amount of sound reflected back to space by the surface enclosing it. This acoustic insulation reduces the sound transmitting into space from an adjacent space though a building fabric. This fabric becomes insulation between walls and air to eliminate air gaps for impact and airborne sound.
Procedure of Acoustic testing:
Some key and important procedures are explained below for efficient acoustic testing:
– Installation of all external construction must be done such as doors, windows, vents etc and doors and windows must be closed.
– Internal doors must be kept open
– All electrical fittings such as lights, fans, switches must be done.
– Make sure that accessibility to both sides of testing walls is done.
– For impact testing there must not be any cosmetic floor fitting
– The testing room must be the one where sound boxes are to be kept in future.
Airborne sound transmission can be tested by placing a test loud speaker which must be capable of generating sound at a range of frequencies. Detection of the sound is carried out over a microphone. Later calculations are made and adjustments are made to account for sound absorption from receiving space. These tests are carried out from a range of 125 Hz to 4000Hz.
