Frequently Asked Questions

Browse our most frequently asked questions below. Please don’t hesitate to speak to one of our expert advisors on 0330 055 7569 or get in touch online if you cannot find the answer you are looking for.

Do you offer a supply and install service?

Yes we offer install only as well as supply and install. Our sister company manufactures acoustic, sound proofing, sound absorption and underfloor heating. Please contact us below for more information.

What geographical areas do you cover?

We can discuss this is more detail, please contact us below so we can assess our project(s) schedule.

How do we obtain a quotation?

If you are wanting to receive a price for a project you’re currently working on, please contact us on 0330 055 7569 alternatively, use contact us online or send us an email at

Do you offer discounted rates?

We do offer main contractor discounts at 2.5%, but nonetheless our technical specialists will be able to put together a system which suits your budget, with value engineering options.

How quickly can you start works?

If you have a tight deadline, contact our Sales team on 0330 055 7569 (Option 1) to check our availability and when we can begin works for your project.

What is the best way to contact the office?

Are the systems you supply & install tested?

UK Acoustic Systems submit all systems to an independent, third party acoustic laboratory for testing. We believe this testing substantiates the effectiveness of the systems. Feel free to contact us for more information regarding acoustic testing.

Do you have any accreditations?

All our accreditations can be found by clicking here.

Can I book in a site visit?

Yes, please contact us online or call 0330 055 7569.

Once you have spoken to our Sales & Technical department, they will be able to arrange a site visit with yourself. During the site visit, our technical specialist and/ or operations manager will be able to talk through the proposed system and timeframes.

Are there any size limitations in relation to the projects you work on?

UK Acoustic Systems have successfully worked on projects that can be classed as large and small. Ranging from 10,000m2 + residential installations to smaller 90m2 hospitality installations.

Please contact us online or call 0330 055 7569.

Are UK Acoustic Systems installers qualified?

Each installer holds a valid CSCS card. They are trained in all aspects of installing acoustics, soundproofing, sound absorption and underfloor heating systems. Further training is conducted at our HQ in Preston as and when new systems are introduced. Alongside our teams of installers we have two dedicated members who oversea projects at install stage. Installation work is checked regularly and health & safety is always adhered to. UK Acoustic Systems hold industry recognised accreditation’s for H&S compliance.

Rw (Weighted sound reduction index (Airborne))

Single number quantity that characterizes the airborne sound insulating properties of a material or building element over a range of frequencies. The figure indicates the amount of sound energy being stopped by the element when tested in a laboratory.

Ctr (Spectrum adaption)

An adaptation of the sound insulation performance curve of an element of structure, used as a correction factor that targets low frequency noise (in particular 100–315 Hz).

Ln,W (Weighted standardised impact sound pressure level (Impact))

Single number quantity used to characterise the impact sound insulation of floors over a range of frequencies. The figure indicates the amount of sound energy being transmitted between two adjacent rooms within a building when tested on-site.

aW (Sound absorption rating)

Single figure rating used to describe the loss of sound energy on reflection at a surface.

Sound Strength dB (Decibel)

A measure of how loud sounds are or sound intensity (abbreviation for decibel).

Decibel (dB)

A unit of measure commonly used to describe the sounds around us (abbreviated as dB). It’s based on a logarithmic scale which means a sound that is 3 decibels higher has twice as much energy.

Echoes (“Hello, Hello, Hello”)

Reflections or repetitions of sound waves. Echoes can be produced by shouting in empty room with solid finishes, (for example, rock, laminate and glass).

Frequency (Low & high)

The number of times a vibrating object oscillates (moves back and forth) in one second. Fast movements produce high frequency sound (high pitch/tone), but slow movements mean the frequency (pitch/tone) is low.

Hertz (Hz)

A measure of frequency, abbreviated as Hz. The number of oscillations (back and forth movements) per second.

Reverberation Time

The amount of time it takes for a sound level to decrease by 60 dB within an enclosure after the sound source has stopped.

Sound Wave

Vibrations of air molecules that travel through air carrying energy with them. Sound waves can also travel through water and solids, but cannot travel in space where there are no molecules to vibrate. When sound travels through air, the molecules do not actually move to a new location, instead each set of molecules “bumps” the molecules next to it, progressively transferring motion to new sets of molecules.

Noise Reduction Coefficient (NRC)

Single value for sound absorption according to ASTM C 423, derived as the mean value of 4 frequencies in the range 250-2000 Hz.

Sound Absorption

Means that sound energy is converted into mechanical vibration energy and/or heat energy. Sound absorption is expressed as the sound absorption coefficient α or the sound absorption class (A-E) according to EN ISO 11654 or NRC/SAA according to ASTM C 423.

Sound Insulation (Soundproofing)

The ability of a building element or building structure to reduce the sound transmission through it. The sound insulation is measured at different frequencies, normally 100-3150 Hz. Airborne sound insulation is expressed by a single value, Dn,f,w, Rw or R’w. Impact sound insulation is expressed by a single value Ln,w or L’ n,w .

Sound Absorption Class

Classification of sound absorbers into Sound Absorption Classes A-E, according to EN ISO 11654, including frequencies 200-5000 Hz.

Class A being the best rating, near 0% reflection.

Flanking Noise

Flanking noise is sound that transmits between spaces indirectly going over or around. Flanking can result from both impact and airborne sounds. Typical elements which cause flanking might include; windows, doors, flanking ceilings/ doors and walls or penetrating joists.

Airborne Noise (Radio & Talking)

Sound or noise radiated directly from a source, such as a loudspeaker or machine, into the surrounding air.

Impact Noise (Footsteps & Banging)

Sound resulting from the impact between colliding bodies.
