The Honeycomb Attenuator is a simple yet effective 3D structure, laser cut from acoustic foam. The W-shaped tiles of foam are tessellated then stacked together, forming a simple honeycomb shape which restricts noise while allowing airflow.
Small, cost effective and flexible, it can be incorporated within the façade of a building (into windows, acoustic vents or within a raised floor) or built into partitions (in a bulk head or standalone
cross talk unit) to enable natural ventilation.
Once installed it allows natural ventilation and heat recovery whilst meeting the acoustic requirements and complying with current regulations such as BB93, HTM and others.
Both external environmental noise and internal noise can be reduced using the Honeycomb Attenuator.
It prevents disturbance and increases privacy and speech intelligibility while allowing air to flow into and around a
building. To listen to the effect of a Honeycomb Attenuator installed in two different buildings in different ways, watch the
videos of a school under a flight path and a busy open plan atrium.
Designed for low energy buildings the Honeycomb Attenuator offers extremely low airflow resistance with better acoustic performance than conventional designs. The attenuator is adjusted simply by extending the length of the design. In this way it can achieve performance levels from 20 dB Dne,w to 40+ dB Dne,w. Each attenuator is manufactured to fit the project needs, but the table opposite provides a range of typical sound reduction levels.
The Honeycomb Attenuator has been designed, developed and produced by MACH Products. MACH Acoustics‘ free design service helps develop the best acoustic design for each building. This includes an assessment of the acoustics and air flow requirements, detailing the optimum length and shape of the unit to meet these needs and establishing the best installation methods. MACH Acoustics will liaise with onsite and design teams and contractors as required to ensure a smooth design and installation.
