Noise exposure files for a polysomnographic study of ground-borne noise from railway tunnels and sleep - Pilot study

Nocturnal airborne railway noise has been shown to be potentially disruptive to sleep, but there is only limited previous research on the effects of ground borne railway noise. This study present laboratory studies investigating how ground borne railway noise at levels occurring in the field impacts on sleep.

Data on sound pressure level, duration and frequency content of ground borne noise from railways were collected from the scientific literature, from measurement reports and by renewed measurements at a few locations in Stockholm, Sweden. The audio files were created to simulate a ground borne noise from a tunnel close to the dwelling. Both files are dominated by low frequencies, but one has more of the lowest frequencies (denoted “LF” in the filename).
