Good acoustics are essential to the way we experience a space.  Whether the space is where we work, learn, exercise or relax, the sound experience is crucial to the way we operate and for our wellbeing.  SoundBlox has over 35 years of experience in developing high quality acoustic materials which not only ensure an optimum acoustic environment in a variety of indoor and outdoor applications but they also fit into any design.

Soundblox - the solution for effective sound absorption

The simple yet highly effective design of SoundBlox acoustic masonry sound blocks make them the ideal affordable solution for reducing reverberation.  They will help you create the right environment in any space, even at low frequencies.

Noise pollution in schools and the workplace - the solution

Noise pollution is a serious issue when considering a person's health and wellbeing yet sound absorption and reverberation control all too often remain as an afterthought.  There have been numerous noise pollution studies that have shown it can have a seriously negative effect on health, school performance, behaviour problems and a persons general wellbeing.  If you consider how much time we spend in the workplace and children at school it's easy to see how the correct acoustic solution can have a positive effect on us every day.

These acoustic masonry sound blocks can be used for all sorts of applications from industrial factories, warehouses, sports halls and gymnasiums to swimming pools.  They can even be used in high noise level environments.  SoundBlox can help to bring noise levels in plant rooms and factories down to managable levels, they can even be used in external road and railway sound barriers.

Acoustic building materials

SoundBlox are made entirely of concrete, this means they are virtually maintenance free; they withstand frequent impact and quietly do their job for the life of a building.  The acoustic blocks have a very 'open' structure, which is needed to ensure optimal sound absorption and reverberation control.  This also has the added advantage that they have a favourable ratio of weight to brick volume, and therefore they have an additional beneficial MKI value.

SoundBlox work by absorbing both direct and reflected sound.  They do this using the Helmholtz resonator principle.  The selection of block, along with the use of rockwool or vitafoam fillers, enables us to adjust absorption characteristics to suit the environment or application.  These acoustic masonry blocks are designed so that they can be laid along with standard masonry blocks and can create complete walls or attractive contrasting panels.

Low maintenance acoustic building blocks

Once installed SoundBlox are resistant to impact damage and require virtually no maintenance.  They're fire resistance up to 2 hours, have a mechanical resistance (strength) of 8-12 N/mm sq. depending upon block selection, and a thermal conductivity rating on 2W(m2K). 

King Ethelbert School acoustic building block case study

We were approached by the King Ethelbert School in Kent.  They felt the acoustics in their sports hall were not up to their high standards, noise levels and acoustic reverberation were reaching levels that were making it hard to teach effectively.  To solve their problem we proposed a combination of SoundBlox and Oscar Acoustics' SonaSpray K-13 Special.  The acoustic masonry building blocks were installed on the lower half on the sports hall's wall. For the upper section, we applied a green SonaSpray K-13 Special coating.  This acoustic solution combination worked perfectly, and the noise levels in their sports hall now remain at an acceptable level at all times.

King Ethelbert School - School Acoustics

King Ethelbert School

Each project is individual; for King Ethelbert School in Kent, acoustic measurements were taken and with purpose designed software an acoustic computer model of the sports hall was created.  This enabled Oscar Acoustics to calculate which areas required treatment to achieve the desired school acoustics.

Industrial noise control

SonaSpray acoustic spray is the perfect solution for industrial noise control.  Quickly applied to walls or ceilings, it absorbs sound energy, instead of reflecting it and significantly reduces noise to create healthier and much safer environments for workers.
