We know that a good night’s sleep is invaluable therefore, any form of continuous or long-term exposure to noise that interrupts our sleep can lead to a significant deterioration in health. The most common type of exposure to noise comes from air conditioners. If air conditioners or ventilation systems are improperly designed, noise from the units takes on the role of a stressor, eventually adversely impacting our wellbeing. In fact, as per the World Health Organisation’s publication on Community Noise, low-frequency noise is considered a daily life stressor.

So, how can we address this? Utilising duct acoustic liners can play a major role in reducing additional noise emissions from air conditioners. However, duct liners typically perform better at higher frequencies ranging from 1000 Hz to 8000 Hz, which does not make them an ideal choice in cases of low noise frequencies such as that ranging from 32 Hz to 500 Hz.

Because higher-frequency sounds contain short sound waves with a frequency of 1000 Hz or higher and low-frequency sound waves range from 32 Hz to 500 Hz, people are more likely to experience noise vibration hums rather than hearing them.

An alternative and far more effective solution to combat this issue is through the utilisation of sound attenuators, which are highly effective in noise control and acoustic treatment of heating, ventilation and air-conditioning units. Specifically designed to reduce the transmission of airborne noise at frequencies ranging from 63Hz to 8000Hz, attenuators provide the ideal solution for air conditioning noise control. In particular, dissipative silencers that are tested to international quality standards and that use a combination of broad and narrow acoustic splitters to control excessive noise (dB) at both lower and higher frequencies, prove to be the most effective method to reduce HVAC noise, helping occupants enjoy a silent and good night’s sleep.
