Noise Reduction Walkie Talkie is a very important communication tool for business. It will help you receive a clear voice from others. Easily filter noisy unnecessary noise. So if you are looking for a walkie-talkie that has a Noise Reduction function, Retevis RB85 will be a good choice.
Not like the normal walkie-talkies, Retevis RB85 uses the IG1202 noise reduction chip, combined with NAU88CAA low-power wideband mono audio codec, to achieve voice noise reduction function. Including the DNN voice noise reduction module, with the standby power consumption of 0.5mW, and working power consumption of 15mW.
So we called Retevis RB85 the AI Noise Reduction Walkie Talkie.
RB85 can realize intelligent recognition including various noise scenes. Such as restaurants, bus stations, subways, railway stations, wind noise, music noise, factory noise, etc.
It is because Retevis RB85 with an intelligent noise reduction chip. This AI processor has performed machine learning on more than 400 million voice data samples( including 200 million foreign language voice samples, can quickly find the most suitable model and parameters for each audio segment through the DNN network.
The core of this noise reduction chip is an AI processor designed specifically for speech noise reduction. The processing output of the original sound is realized through a 3 layer deep learning network. And Each layer of the network has 1028 nodes. In addition, the calculation of this AI processing can reach 1012ops/W, and specially compressed sound signals.
Generally Speaking, We usually use the SNR to judge the noise reduction function. SNR is a single-value noise reduction value tested in accordance with the international standard ISO 4969-2. The higher the SNR ratio of the device, the less noise it produces. We can know the SNR of RB85 from the below chart comparison. When turning on the noise reduction function, the noise has been greatly improved.
| Noise Type | Before treatment SNR(dB) | After treatment(dB) | Before and after the upgrade(dB) |
| Animal sound | 0 | 15.16 | 15.16 |
| 10 | 18.26 | 8.26 | |
| Noise from household appliances | 0 | 10.95 | 10.95 |
| 10 | 16.61 | 6.61 | |
| Music Noise | 0 | 13.55 | 13.55 |
| 10 | 18.53 | 8.53 | |
| Party restaurant noise | 0 | 14.09 | 14 |
| 10 | 18.8 | 8.8 |
So RB85 is the best AI Noise Cancelling 2 way Radio.
