Outdoor noise reduction leisure seat based on sound subjective intervention

Abstract

The invention relates to an outdoor noise reduction leisure seat based on sound subjective intervention. The outdoor noise reduction leisure seat comprises a sound insulation mechanism and a sound subjective intervention mechanism, wherein the sound insulation mechanism comprises a bracket, a seat (5) arranged on the bracket and a noise reduction seat back (2) arranged on the back side of the seat (5), and sound insulation side plates (9) are further arranged on two sides of the noise reduction seat back (2); the sound subjective intervention mechanism comprises a loudspeaker (3) arranged on the noise reduction seat back (2) and a subjective intervention sound storage file connected with the loudspeaker (3). Compared with the prior art, the outdoor noise reduction leisure seat is provided based on theories of acoustic noise reduction and subjective perception of acoustic environment of the crowd and the like, a comprehensive technology of active and passive sound insulation and noise reduction and sound masking is used, the subject comfort of seat users is improved, and thus the crowd get a quiet in the increasingly noisy dense city.

Description

technical field [0001] The invention relates to an outdoor seat, in particular to an outdoor noise reduction leisure seat based on acoustic subjective intervention. Background technique [0002] The problem of environmental noise in dense cities is prominent. Traffic noise along roads and aircraft noise around airport routes have seriously affected the health of the outdoor public. In the noisy environment of the city, try to let the crowd relax for a moment on the waiting chairs at the bus station or the leisure seats in the green park residential area under the airport route, that is just a "castle in the sky". At present, most of the leisure seats are L-shaped, and the function is mainly for sitting, but it does not consider the interference of other environmental factors in the space where it is located. Based on the research on the subjective perception of the acoustic environment, the public will choose to spend more time in comfortable and quiet areas for short-term ...

AI Technical Summary

Problems solved by technology

[0003] After investigation, there is almost no research on outdoor seats that can independently reduce noise interference. Most of the literature focuses on the research and development of noise reduction functions for indoor and compartment seats. Public green spaces, parks, residential areas, and buses with high environmental background noise In the station, the public will feel restless, which is not conducive to public rest and relaxation, and reduces the comfort of leisure seats
