  1. 1. Acoustic Characterization of Catalyst

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Surachit Dokson; [2023]
    Keywords : ;

    Abstract : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. READ MORE
