Problems solved by technology

[0003] Many passengers use the method of listening to MP3 or other music players in an attempt to use the sound of music to cover the noise to resist the irritability caused by noise. Can damage human hearing and cause noise-induced deafness
The currently known effective method is to wear noise protection earplugs or earmuffs to greatly reduce noise. This method has been proved to be effective, but when taking public transportation, passengers have to receive public transportation information, such as the arrival location of the vehicle , and the noise protection earmuffs / earplugs shield the broadcast information of the public transportation system at the same time, causing passengers to worry about whether they will pass the station when taking the public transportation system and cannot ride with peace of mind. In addition, the noise protection earplugs must be taken off when passengers make a phone call , still can not solve the problem that passengers cannot hear the other party's voice clearly due to the excessive noise on the phone on the public transportation system

Embodiment 1

[0032] Embodiment 1: A noise reduction system used on a bus.

[0033] as attached figure 1 As shown, the public transport information sending module is installed on the bus station and the bus, and sends radio information (or sends information through other media) to the outside in real time. At the bus stop, this information can include relevant bus information, such as which vehicles stop at the station, the expected arrival time of each bus vehicle, the vehicle will arrive at the station immediately, and each vehicle will go to the station, emergency information, such as emergency evacuation message Wait. At the bus vehicle, the information may include related bus information, such as the direction of the vehicle, the name of the next stop of the vehicle, the estimated time of arrival at the next stop, the estimated time of arrival at the designated stop, emergency evacuation due to vehicle failure, etc. The sent information may be text information and / or voice informatio...

Embodiment 2

[0050] Embodiment 2: Another noise reduction system used on a bus.

[0051] as attached figure 2 As shown, the microphone module and voice playback module are integrated into the anti-noise earmuff body to form a whole A, and the remaining modules (public transportation information receiving module, information processing module, user interaction module, information storage module, card swiping module, and mobile phone communication Module) is integrated into a whole B, B can be hand-held, A and B are respectively equipped with receiving / sending devices to realize information communication between A and B, for example, B sends relevant information to A through the receiving / sending device, and A Play relevant sound information through the voice playback module; when making a call, A records the user's voice information through the microphone, sends it to B in real time through the receiving / sending device and then sends it to the mobile phone, and receives the mobile phone th...

Embodiment 3

[0053] Embodiment three: as attached image 3 As shown, in order to facilitate the user's query of the public transportation system, optionally, the system also includes a public transportation information query module, and the public transportation information sending module and the receiving module are respectively changed into the first public transportation information receiving / sending module and The second public transportation information receiving / sending module, the two receiving / sending modules realize the information interaction between the public transportation information query module and the user terminal information processing module, the user sends a route query request to the public transportation information query module, and the public transportation The information inquiry module sends relevant public transportation information to the user through the first public transportation information receiving / sending module and the second public transportation inform...

Abstract

The invention discloses a noise reduction system for public transportation. The noise reduction system for public traffic particularly comprises a public traffic information transmitting module arranged in a station and / or a public transportation vehicle, a noise resisting earflap body worn by a user, a public transportation information receiving module, a user interaction module, an information processing module, an information storage module, a microphone module and a voice playing module. By arranging a plurality of modules in a general noise reduction earphone, the information interaction between the general noise reduction earphone and the public traffic system is realized, and a user can obtain necessary information while outside noise is fully shielded and the self immersion of the user is facilitated.

Description

technical field [0001] The present invention relates to a noise reduction system, and more particularly to a noise reduction system used in a public transportation system. Background technique [0002] The noise levels generated by public transport in cities are high enough to cause permanent hearing damage. It is estimated that the hearing of about 30 million people in the world is damaged by noise. Scientists measured the noise level of New York's public transportation system and found that among vehicles, the subway reached 80.4 decibels, and the light rail also had 79.4 decibels; the stations were even noisier, with subway platforms reaching 102.1 decibels and bus platforms reaching 101.6 decibels. my country's current "Technical Conditions for Motor Vehicle Operation Safety" stipulates that the noise next to the driver's ears is not higher than 90 decibels, and when driving at a constant speed of 50 kilometers per hour, the noise inside the car is not higher than 79 de...
