Fig. 2 Spectral analysis for female subject reading in quiet conditions
Fig. 3 Spectral analysis for female subject reading while listening pop music
determined that the sound intensity of their speech was increased with over 40%
when listening to pop music.
Surprisingly, the construction site noises did not lead to very high levels of the
intensity, nor the white noise. For both, a growth of less than 10% was recorded. In
Fig. 6, the values of the average sound pressure for each of the ten subjects in all
four conditions were represented.
By analyzing the diagram, it becomes obvious that all the subjects slightly
increased their speech intensity with construction site and white noise, but the growth
is more dramatic in case of the pop music (purple columns). The reason might be the
fact that human mind tends to listen when hearing another human voice, to a much
greater extent than hearing another type of sound. It is much easier for a person
to filter random unpleasant noises than human voices. For this reason, reading on
