一、 前言 西安变压器电炉厂发电机房噪声级高达100分贝以上(A声级),长期工作在发电机房的工人对此反映较大,曾多次要求进行噪声治理,为此,曾在发电机房内建立过一个隔声室供工人休息之用,但由于选用的隔声结构不合理,隔声效果不好,隔声量只有10分贝,未能解决基本问题。这次结合噪声防治试点,对发电机房的噪声问题再次进行全面防治。经与该厂和省市劳保部门共同研究决定,仍在发电机房内建立一个隔声性能较好的隔声室,为机房工作人员提供一个防止噪声危害的掩避所,根据原有发电机房实际情况,对隔声室拟定如下基本要求:
First, the foreword Xi’an transformer furnace plant generator room noise level up to 100 dB (A sound level), long-term work in the generator room workers reflect this, has repeatedly asked for noise control, for which, in the power generator room An acoustical chamber was set up for workers to rest. However, due to the unreasonable structure of sound insulation used and the poor sound insulation, the sound insulation volume was only 10 dB, which failed to solve the basic problems. This time combined with the pilot of noise control, the noise of the generator room will be completely prevented and dealt with again. After the plant and the provincial labor department jointly study and decide, still in the generator room to establish a sound insulation performance better soundproof room for the engine room staff to provide a shelter to prevent noise hazards, according to the actual generator room Situation, the soundproofing room to develop the following basic requirements:
