Heating, Ventilation & Air Conditioning (HVAC) sound level measurements

Commercial air-conditioning or HVAC systems (Heating, Ventilation and Air Conditioning) often generate and transfer noise which frequently becomes a source of disturbance in sensitive residential or commercial areas and needs to be measured.

ALPHA Acoustiki’s engineering team has significant experience in such measurements and engineering solutions in HVAC applications. We can carry out sound level measurements for HVAC equipment such as outdoor chillers, water pumps, blowers, fans, AHUs,compressors and many other noisy indoor and outdoor HVAC units.

Using our findings and sound level results from the on-site noise measurements, we propose the optimal acoustic engineering modification strategy for each case.

Our services include, but not limited to:

– Spectral noise analysis throughout the audible frequency range (from 31.5 to 18,000 Hz).
– Ambient noise measurements such as Leq, Lpeak, LAFmax, LAFmin, LAF10, LAF90
– Environmental noise measurements and noise mapping.

Most common problems occur when mixing residential and industrial applications within urban areas. Specifically, coolers, VRV, heat pumps, server rooms and other equipment that operate a 24/7/365 basis often disturb neighbouring houses.

We perform noise measurements of HVAC systems or other mechanical equipment to classify the noise emitted to the residents, but also within the company area itself.

Our company submits the corresponding technical report with noise values compared to the national or international limits in dB, including corresponding problem-solving solution where this is necessary. Soundproofing recommendations take into account not only the needs for soundproofing but also the mechanical constraints required in each application. Such constraints are usually the ventilation needs, maintenance or visitation needs of each equipment, and the structural constraints presented in each project.
