Kebisingan adalah bunyi atau suara yang tidak dikehendaki dan dapat mengganggu kesehatan dan kenyamanan lingkungan yang dinyatakan dalam satuan desibel ( dB) .

Umumnya sumber kebisingan dapat berasal dari kegiatan industri, perdagangan, pembangunan, alat pembangkit tenaga, alat pengangkut dan kegiatan rumah tangga.

Untuk mengetahui intensitas kebisingan di lingkungan kerja digunakan alat yang disebut Sound Level Meter. Salah satu alat untuk mengukur kebisingan adalah Merk PCE.

PCE 353 is the possibility to measure the level of continuous acoustic pressure ( LEQ) , this sound level meter is suitable for making checks in workplaces, of machines, etc.
It has an analogue output that makes it possible to record the values in external places ( p.e. for CE certification according to the guidelines for machines) .
Stored data can be easily transferred to a PC via the RS-232
interface and analyzed using the software ( English) and a cable provided.
