Low Frequency Noise Annoyance

Low Frequency Noise (LFN) can be an environmental noise problem. Not everyone can hear it, as our range of hearing differs, and in many cases no source can be identified. It is frequently perceived as a throb or low rumbling or referred to as a ‘hum’. As well as causing irritation and annoyance, LFN can disturb sleep and make people uncomfortable in their homes. This Briefing Note looks at LFN, how it impacts those affected by it, the challenge of identifying where it comes from and what can be done to address the impacts.
