A company manufactures roof tiles to many styles. The de-palleter is a vibrating plate that shakes roof tiles free from moulds. An acoustic enclosure had been fitted, but as most of the noise was generated at the point where the tiles part with the mould, i.e. at the outlet where there was a large aperture in the enclosure. The acoustic enclosure did not seal particularly well and most of the catches were broken. The noise level at the operator's position was 92dB.
The operator's noise level was reduced by 4dB to 88dB.
