Observation room for anti-noise production site

Abstract

The invention discloses an observation room for an anti-noise production site. An inner observation room is positioned in a vibration eliminating unit in an existing observation room, wherein the inner observation room is not in contact with the existing observation room. The vibration eliminating unit comprises a support frame connected with the bottom of the inner observation room and a plurality of inflatable vibration damping pads arranged around the support frame and in contact with the ground. The observation room changes the mode of adding sound insulation to the existing observation room in the prior art, and the inner observation room installed on the vibration eliminating unit is arranged in the existing observation room, through the cooperation of the support frame structure ofthe vibration eliminating unit with the inflatable vibration damping pads and a sound absorption and insulation structure of the bottom plate, the influence of solid sound transmission is reduced, andthe design of the four walls and the top structure of the inner observation room further reduces the air noise, the sound in the inner observation room is between 20-40 dB, the inner observation roomis extremely quiet, and the harm of noise in the observation room is completely solved.

Description

technical field [0001] The invention relates to a production site observation room, in particular to an anti-noise production site observation room. Background technique [0002] The observation room of the production site is a must for many production enterprises. It adopts a civil structure. It consists of a concrete room combined with the workshop, monitoring equipment, testing instruments and an observation window facing the workshop. The lower part of the concrete room is generally installed. Wooden floor, various pipelines run under the wooden floor, and personnel are placed in the room for on-site observation. [0003] Since the observation room is located in the factory building, various noises cause the indoor noise to seriously exceed the standard. In order to solve the problem of excessive noise, the existing technology uses sound-proof doors and sound-proof observation windows to reduce indoor noise, and even installs sound-absorbing layers on the walls. .

AI Technical Summary

Problems solved by technology

However, the result of these treatments is that the maximum noise reduction ability is only 34-36dB, resulting in many cases, the indoor noise is still at 65-71dB

[0004] When it is more serious, even if we reduce the noise to 60db, since the observation room is a civil structure, there are various solid-state sound transmissions, which cannot be solved by the above-mentioned structure and method. However, the sound-absorbing and insulating structure and the method of reducing noise in the existing technology cannot solve the problem of solid-state sound transmission, which leads to different degrees of occupational diseases (such as hearing loss, neurasthenia, etc.)

[0005] In order to solve this problem, the existing technology has carried out various explorations, and wants to make a silent observation room to ensure the physical and mental health of the staff. However, although these explorations have reduced the impact of part of the noise, they cannot remove the solid-borne sound. long-term impact, therefore, the existing technology does not address this issue
