Moreover, the concept of what painful noise is will be developed, applied to this context. After Ergonomic Work Analysis [2], the following variables were selected to characterize the painful noise: volume, height, frequency, sound confluence and reverberation. To relate the influence of painful noise on modes operatives, were explained the operative strategies used by teacher and students during the performance in group of this Big Band.
