Скачать или смотреть Newtown Bypass noise with ground compaction in progress

Noise level shown on spectrum analyser. Calibrated microphone used. Raining heavily so noise from Brook is higher than normal.
This measurement concurs with my CLIO measuring system.
Noise is principally extremely low frequency and at about 30dB above ambient norms. Display shows a steady sinewave only produced when ground compactor is running. Please bear in mind that this is measured INSIDE the house, with double glazing. Much of the noise seems to come through the floor and walls. Objects and windows in bedrooms are vibrating in sympathy. This level of vibration must surely be adversely affecting both my house and those of the other residents of Bont Dulas.
The low frequency sound level in the house is unbearable.
