Acoustics in Ventilation — Taming the Low Frequency Roar
Online | Recording
Can we really be affected by something we cannot hear or feel in a building? Recent research has shown that low frequency noise could be a considerable contributor to people's health problems caused by poor indoor environments in buildings. How can we manage something that is inaudible and barely measurable?
To maintain good indoor environmental quality (IEQ), we consider air quality and temperature as the most important factors. However, sound pollution and noise control have received significantly larger attention as we become increasingly adept at insulating our buildings and thereby removing noise from the outside environment. As a result, we are even more sensitive to the sound generated by the building´s installations. In the field of sound, low frequency noise is one of the significant challenges in the HVAC industry.
In this webinar, we will explore the importance of understanding low frequency sound in ventilation systems.
- Why indoor environment and ventilation matter?
- Low frequency sounds (including infrasound) and their sources in ventilation systems.
- Noise ratings and sound criteria in acoustic designs.
- Research and case studies on low frequency sounds.
- How does it affect human well-being and health?
- Strategies for mitigating low frequency noise in ventilation systems.
