Friends, there is a sound that I think of the front console of the vehicle. When the vibration sound gets on the load, there is a hum of 1500 to 2000 cycles. The console was dismantled, tried and ripped again. There is no place to experience. Previously, we removed a TL from the heating system. Vibration in the room was making sound. Then after removing and wearing the chest, the sound I was looking for now appeared. Do you have any wrists that experience? https://youtu.be/NO1EyhLPSgo Video linkirtek792020-05-30 10:37:52
