Noise Testing Specialty Areas
- Personal Noise Dose Monitoring We conduct accurate assessments of individual noise exposure levels using dosimetry, ensuring workers are protected from the health risks associated with prolonged or excessive noise. These results support compliance with workplace noise regulations and help inform hearing protection strategies.
- Factory and Machinery Noise Assessment Our team evaluates noise levels generated by factory processes, plant equipment, and industrial machinery. We identify high-noise areas and recommend practical noise control solutions to improve the working environment and reduce the risk of hearing damage.
- Environmental Boundary Noise Monitoring We assess noise emissions at the property boundaries of industrial and commercial facilities to ensure compliance with environmental noise regulations. Our assessments help mitigate the impact of operational noise on surrounding communities and support resource consent requirements.

FAQs
What are the legal noise exposure limits in NZ?
According to WorkSafe NZ and AS/NZS 1269.1:2005, the key exposure limits are:
- LAeq,8h = 85 dB(A) (average noise over an 8-hour day)
- LCpeak = 140 dB(C) (peak/instantaneous noise level)
If noise exceeds these limits, control measures must be implemented.
What types of monitoring do you do?
- Personal noise monitoring using dosimeters worn by workers
- Static/area monitoring using Class 1 sound level meters
- Octave band analysis to assist with selecting appropriate hearing protection
- Boundary monitoring for environmental or community noise assessments
