Résumé

Current low frequency noise (LFN) assessment guidelines and their use in environmental noise impact assessment were discussed. LFN generally covers noise in frequencies below 100 to 150 Hz. Infrasound LFN can produce resonances in human organs and tissues. LFN annoyance research suggested that for humans the doubling rate of perceived loudness was 4 to 5 dB for LFN vs 10 dB at 1 KHz.
