From the latest INAIL report : "In Italy the average level of sound exposure of operators of the call center was estimated around 80 weighted decibels (dB(A)), a level of exposure to noise that Article 189 of Legislative Decree 81/2008 considered already at risk. For 20% of employees exposure was even greater." Risks are many.
The lack of attention of the acoustic control within the call center and offices is a source of risk to the health of workers. The acoustic correction, besides enjoying tax incentives, sometimes have extremely limited costs in relation to benefit.
Too often, Italian workers in call centers operate in conditions which do not comply with what is required by the first rules on security. Call centers are confined and overcrowded spaces, where the acoustics becomes really bad: the background noise of the conversations, if unshielded, triggers the inevitable consequence of raising the overall tone of voice, thus an overload on vocal cords. The wall constant sound, to which the operator is exposed for hours and hours, is heavily damaging.
Exposure to loud or prolonged noises causes damage to their hearing, up to deafness, but also stress and damage to the nervous system.
The need is therefore to have an "acoustic control" within the environment to avoid interference between the various telephone operators'stations. In Call Centers, activity is based on speech and the two causes of disorder are:
1) The direct transmission of the sound energy produced by the operators.
2) The reflections of the sound energy from part of the ceiling and walls.
The main indicator of the acoustic characteristics of a confined environment is the "reverberation time". Its measurement indicates the consistency of the problem and allows technicians to 2B resins to design appropriate solutions.
To solve the problem of interference between locations and reduce them considerably,2B resins suggests the adoption of protective screens between the operators' desks.
To delete the reflections of the sound energy on the structures, we must instead work with the application of absorbing units to the ceiling as the panels in the image below, or with adequate false ceilings.
Where it is necessary to create environments or intervene on existing walls, can be used the HABITAT system tested by 2B Resine, consisting of a self-supporting acoustic insulation panel coupled to plasterboard sheet , used for the creation of acoustic walls overlaying the existing ones.
