Noise

Noise within the office can originate from internal and external sources. Internal noise sources include office equipment such as telephones, printers and photocopiers, people and background noise generated by the building from lifts and air conditioning. Background noise generally goes unnoticed unless there is a malfunction of equipment. External noise sources may include road traffic and general industrial noise.

Generally, the levels of noise in office areas are below those levels known to pose a risk to hearing. In offices, 'annoyance' noise is likely. This level of noise may annoy or distract people, interfere with communication, and affect performance of tasks like reading and writing. Noise that prevents a person from understanding an instruction or warning signal may also be a risk to safety.

Identifying disturbing noise in the office

To identify disturbing noise sources in an office the person conducting a business or undertaking may:

• ask the workers about the noise
• consult a qualified person.

To control unwanted noise in the office consider:

• selecting equipment with the lowest noise specifications practicable
• the orientation of workstations
• sound-absorbent materials, including suitable floor coverings, wall panels, ceiling panels and dividing screens
• separating noise generating activities or equipment from tasks requiring concentration
• isolating noisy equipment such as printers or photocopiers by placing them in separate rooms
• acoustic hoods on noisy equipment
• installing noise barriers including double-glazed windows, solid walls and fences to reduce external noise sources
• lowering the volume setting on disruptive telephones
• using meeting areas away from work areas.
