Noise levels are not enough to assess completely the influence of the noise. Therefore, psychoacoustics and perception surveys should be taken into account. The noise that the construction workers produce in their tasks is recorded with a HATS. Later, those recordings are processed to derive different parameters: spectrum, weighted equivalent levels, and the main psychoacoustics parameters. After that, a specific survey has been developed to assess the perception of such activity noises during the working time to correlate adjectives of perception with those parameters mentioned. The survey has been designed to be answered by the workers that are exposed to the noise, so that conclusions could be derived about the feelings and annoyance that the noise can cause.
