Put Whisper on the wall if you have nowhere to hide the noise
Nowhere is noise in life No, even in the house, you may be disturbed by various outdoor noises. When the window is open, you can also reduce the noise by closing the window, but if the windows are closed, how to eliminate the noise? All that is left is to plug the ears. However,Micro Sound TechnologyWant to give the public a new choice in this situation, that is, theyWhisper the Noise Canceler is crowdfunding on Kickstarter indoor Noise reduction equipment.
Whisper the Noise Canceler looks like two flat plates, When in use, it is fixed on both sides of the glass or wall, one is outdoors and the other is indoors. The outdoor unit collects outdoor noise and transmits it to the indoor unit through Bluetooth. The indoor unit is based on active noise reduction technology and emits sound waves that are opposite to the noise. Cancel the noise entering the room.
Whisper has wide operating frequency in noise reduction and has feedback adjustment function. Whisper can reduce noise in the frequency domain of 200-14000Hz, which is wider than most active noise reduction devices. The founder, Mr. Meng, told 36Kr that the consumer-grade active noise reduction headphones with the highest nominal specifications on the market can achieve 4KHz noise reduction. When the frequency is higher, it will be limited by the chip and circuit frequency. Whisper passed them The unique algorithm realizes the work in the high frequency band. The Whisper indoor unit also has three error detection microphones, which compare the noise reduction results with preset thresholds and give feedback to the error. By adjusting the output amplitude and frequency phase, the final noise reduction effect can be adjusted.
The specific noise reduction effect, from the video on Kickstarter, the Whisper is installed on both sides of a door. When the door is open, the indoor volume is 66-72 decibels, and when the door is closed and the Whisper is not opened, the indoor volume is reduced to 54-60 decibels , After turning on Whisper, the indoor volume is around 40 decibels.
Weisheng Technology has a company in China and New Zealand. At present, the team has only three full-time employees and has been using its own funds for product research and development. Whisper is currently crowdfunding hundreds of new coins on Kickstarter, which is a bit expensive. Microsound Technology stated that it mainly wants to pass the crowdfunding test under the market acceptance and adjust the product according to the situation. In the future, they also plan to crowdfund again on Indiegogo, when product features and prices may be adjusted.

60 square meters.固定时，平板的内侧可以用吸盘固定在玻璃两侧，或者通过钉子等固定在墙的两侧，微声科技表示使用的吸盘可以保持非常长的时间，没有强外力作用，可以长期保持紧固，不会像真空吸盘因密封不严而松动。墙的厚度大时，内外的机器就不能互相充电以及通过蓝牙传输数据，但使用USB线缆把室内机和室外机连接起来，降噪功能依然可以正常使用。
微声科技在中国和新西兰各有一家公司，目前团队全职员工只有三人，一直在使用自有资金进行产品的研发。目前Whisper在Kickstarter上众筹价数百新币，稍显贵，微声科技表示主要是想通过众筹测试下市场的接受程度，并根据情况对产品进行调整。未来他们还计划在Indiegogo上再次众筹，届时产品功能和价格可能会有所调整。
