Diamond Blade Drilling (Plumbing Renovation)

The audio was recorded in an apartment during the plumbing renovation work in the building. The loudest sound that can be heard is a diamond blade drill which is used to drill holes into concrete walls for the plumbing tubes.

The actual work was done outside the apartment but the noise reached the level of 80 decibels, which is the limit of a noise that can be thought of as potentially hazardous.

The drilling is made in short intervals probably because of heating of the drill blade but possible because of the noise. Between the drilling you can hear the workers moving their tools and gear around in the corridor.
