Attenuated passive ventilation options

With the advent of the guidance in ProPG: Planning and Noise, there is an increased need for sound attenuated passive ventilation to achieve reasonable internal conditions in dwellings, considering noise, ventilation, and overheating.  The first stage of the acoustic assessment described by ProPG is to apply the principles of good acoustic design; this includes the…

Good acoustic design: a case study

STOP PRESS: Currently shortlisted for the environmental acoustics award! The priority of good acoustic design is to reduce the need for acoustic façade treatment by considering the building locations and orientation, internal layouts and mitigation for controlling noise at source. This example of good acoustic design is a housing development in Swanley, Kent, UK. The proposed…

Noise, ventilation and overheating in dwellings

Apex has been researching and disseminating information for many years advocating an integrated approach to assessing acoustic conditions in dwellings in combination with ventilation conditions and considerations of opening windows.  This work has now been taken up by an industry-led committee through the Association of Noise Consultants, called the “Acoustics, Ventilation & Overheating Group”.  The committee…

Noise and ventilation in dwellings

The combined issue of noise, ventilation and thermal comfort in dwellings is very significant for occupants, yet currently under-researched and poorly understood even within our industry.  Current requirements for noise levels described in planning conditions, British Standards and WHO Guidelines are not associated with either ventilation conditions or thermal comfort levels.  Apex has been leading…

VHF and Ultrasound exposure: do we know the risks?

Incidental public exposure to VHF (Very High Frequency) sound and Ultrasound has increased dramatically in recent years due to sources such as the testing of public address systems and pest deterrents.  Research into potential health effects and regulation of public exposure has not kept pace with these developments.  The majority of the studies used to…
