Rumore - dove non lo incontriamo?

Sia sul posto di lavoro che nell'ambiente domestico, nei mezzi di trasporto pubblici, nei viaggi in aereoplano, in ferrovia o in pullman - esso ci accompagna dovunque.

Gli effetti negativi di questi rumori fastidiosi sono comprovati da studi effettuati e anche ciascuno di noi li avrà già provati.

￿nervosismo

￿mancanza di concentrazione

￿irritabilità...

sono solo gli effetti più appariscenti sull'organismo. Il rumore agisce inoltre sul sistema neurovegetativo e può provocare danni permanenti all'udito.

Le fonti di rumore sono molteplici e troppo spesso non eliminabili per il singolo individuo. Per questo motivo solo la protezione personale in un luogo rumoroso può rappresentare una soluzione.

Con il sistema NoiseGardla Sennheiser ha realizzato una soluzione efficace. Il principio di funzionamento e l'impiego Vi vengono spiegati in queste istruzioni.

L'unità di misura per il livello di pressione acustica è il decibel (dB). Un'attenuazione del rumore di 10 dB viene generalmente percepita come un dimezzamento del volume, un'attenuazione di altri 10 dB fornisce una percezione sonora ridotta del 75% ecc.
