A cutting-edge solution to ‘reverberation woes’
AG, a supplier of hard landscaping, building, and structural pre-cast products, describes its Alphacrete Acoustic as ‘a cutting-edge, soundabsorbing masonry block with outstanding room and building acoustic performance’.
he company explained: “Alphacrete Acoustic was expertly developed to offer higher levels of sound absorption than standard masonry blocks, meaning that it effectively reduces airborne noises
and excess reverberation. Additionally, the flutter echoes and standing waves produced by reflective parallel wall surfaces will be significantly reduced.”
AG says Alphacrete Acoustic ‘offers a solution to those tasked with dramatically improving speech intelligibility and acoustic performance in conventional constructions where reverberation causes problems’. Independently tested by Sound Research Laboratories to prove it meets the acoustic performance standards for a Class D sound absorber according to BB93:2015, it is also ‘extremely strong and durable’, and ‘non-combustible’. The blocks do not require plastering, painting, or ‘the addition of the expensive soundabsorbing wall panels typically required to achieve Part ‘E’ compliance with standard block or brick constructions’.
The block is available in two distinct finishes, Athena and Corinthian. Athena is smooth and stronger in colour, while Corinthian ‘has added texture and natural colour variances’.
