HVAC & Building Services Acoustics | Duct Noise and Plant Room Measurement

HVAC acoustic measurement addresses duct-borne noise, fan noise characterisation, plant room emission levels, and noise breakout from building services equipment. Compliance with NR/NC criteria and building regulation requirements is supported.

• Fan and air handling unit noise characterisation
• Duct insertion loss measurement and breakout assessment
• Plant room emission level surveys
• NR and NC curve compliance measurement in occupied spaces
• ISO 5136: In-duct sound power determination
