17 The human organism is not ‘made’ to deal with loud and aggressive, constant noises. Indicatively, we present a table with common daily sounds. Sound description Sound volume in (dB) Leaves blowing in the wind 20 Interior of a quiet home 40 Store or shop 70 Busy street 80 Thunderbolt 100 Concert - Club 120 The impact of noises on humans depends directly on the frequency of exposure of each individual to them, the duration of the exposure and their physical condition. Children are more sensitive to noises. Protect them, ensuring acoustic comfort conditions, at least in their home. 68dB 80dB 71dB 81dB 74dB 85dB 77dB 130dB According to allowed noise limits, sounds that do not exceed 68dB, characterize the sound environment as Comfortable. Sounds up to 80dB, characterize the sound environment as Very noisy. Sounds that do not exceed 71dB, characterize the sound environment as Good. Sounds exceeding 81dB, characterize the sound environment as Aggressive. Sounds that reach 74dB, characterize the sound environment as Tolerable. Chronic exposure to noise levels above 85dB leads to loss of auditory acuity. Sounds that reach 77dB, characterize the sound environment as Noisy. It is the level where sound causes pain and can lead to the rupture of the ear drum. From acoustic comfort to noise ADJACENT ROOM ADJACENT ROOM ADJACENT ROOM AIRBORNE NOISE IMPACT NOISE
