ERVs contain fans and moving air, so some operating noise is unavoidable. The perceived noise depends on fan speed, unit design, installation quality, duct sizing, airflow velocity, vibration isolation, and the location of the unit.
Appropriate duct design, acoustic treatment where needed, vibration isolation, and correct airflow balancing can help reduce noise at occupied spaces.
When comparing models, check the stated sound level and its test conditions, and distinguish unit sound pressure from sound power and installed room noise.
