Frequently Asked Questions - Sound Testing

What is sound insulation testing?

Sound insulation testing is an acoustic testing procedure is conducted to check whether the elements of the residential dwelling are offering acceptable sound insulation in accordance with Building Regulations Act Part E.

As a part of the testing procedure, an acoustic professional measures both airborne noise (noise that is transmitted through the air such as music, conversions) and impact noise (noise caused by an impact such as footsteps on the floor). To comply with Building Regulations, a residential dwelling must offer sufficient resistance and insulation for both types of sounds.

Is sound insulation effective?

Absolutely. Even if you are residential dwelling doesn’t happen to provide sufficient sound insulation, our expert acoustic consultants at Southern Sound Testing can help you bring down the sound insulation of your residential dwelling to the acceptable levels.

What is Soundproofing?

Soundproofing is a process of blocking noise from leaving or entering the room using insulative materials that reduce or absorb sound. Soundproofing can be classified broadly into two categories:

  • Soundproofing to improve the sound quality inside the room while insulating it from unwanted external noise.
  • Soundproofing a room or home to minimize the sound leakage between rooms using a variety of sound-insulating elements like doors, windows, like ceilings or floors.

Why test Soundproofing?

Testing the effectiveness of soundproofing is absolutely essential to help the acoustic design professionals to achieve an adequate level of sound insulation.

Can soundproofing be tested?

Acoustical testing can be used to test the soundproofing effectiveness before and after the modifications are made to the structure. Majority of soundproofing materials used to soundproof the room have a dB rating which indicates the effectiveness of sound insulation provided by the specific material. Higher the dB rating of an insulation product, better it’s soundproofing capacity.

What is acoustics testing?

Acoustic testing is a test devised and performed by acoustic professionals to determine the sound/acoustic impact of a project on its surroundings.

What is the purpose of acoustical testing?

Acoustic testing is important to make sure specific the new build’s sound insulation levels are in accordance with Part E of Building Regulations to ensure a minimum standard of living for the occupants.

Our Acoustic engineers at Southern Sound Testing now offers a comprehensive acoustic consulting and sound testing services right from the initial building stages to its completion in order to make sure your building complies with all the Building Regulation standards.

What is Direct-field acoustic testing?

Direct-field acoustic testing is an on-site acoustic testing technique where an acoustic environment is simulated by a portable system of acoustic drivers around the testing object. Benefits of Direct-field acoustic testing is the portability of the test equipment which can be transported and set-up at any location to perform the acoustic testing.

How do you calculate the noise?

Noise is the unwanted sound at a specific location and the loudness of this sound is quantified in terms of the sound pressure. This sound pressure is measured in decibel (dB) by a sound level meter.

How is the impact noise measured?

Impact noise is the noise generated by the impact (foot tapings on the floor) and it is measured by using a tapping machine which creates an impact of different intensities on the floor above. The pressure levels of these impact sound generated are taken in the receiver room in at least 5 different positions to measure the impact noise.
