If the noise from your bluetooth receiver is very different than what I have suggested, it could be either your bluetooth receiver is defective, or it's simply too cheap. This two types of noise actually corresponds to different problem of your system and it is possible for both noises to occur. I have made audio demonstrations for your reference. Generally speaking, there are two types of noise can occur with the Bluetooth audio receiver: It will be brilliant that we can read till the end of this post as I would love to share my personal best solution for building a Portable Bluetooth Speaker for discussion! Identifying the problemFirst of all, we need to identify which types of noise occurs on your system. Therefore, 7 months later, I am here to share my solutions that might eliminate the noise from your Bluetooth audio receiver. I know that there are a lot of people working with bluetooth audio receiver had faced the same problem, then ended up using a more expensive bluetooth module. ![]() Recently, out of some random chances, a professor from my university mentioned sth about common mode choke, said that it is a component to build a EMI filter, and that's literally how I find the solution to my problem. Unfortunately, none of the solutions in the thread can fully eliminate the noise, and I also didn't find any solutions from the forum. Greetings! About 7 months ago, I posted a thread about the noise from a bluetooth audio receiver. Most power companies will investigate the problem and take steps to correct it.This is an old thread, an industrial solution is found. If you cannot determine the source of the electrical interference, contact the customer service department of your local power company. If you cannot locate the interference source in your own house, check with your neighbors to see if they also experience interference. The closer you get, the more intense the static will be. You should hear static or a buzzing sound as you get close to the source of the interference. Interference caused by your power company's electrical equipment is normally continuous, and your power company should be notified.Ī simple method of determining the location of electrical interference is by using a portable battery-powered AM radio tuned to a quiet frequency at the lower end of the dial. This interference may be caused by equipment in your home, such as hair dryers, sewing machines, electric drills, doorbell transformers, light switches, smartphone chargers, power supplies, computing devices, washing machines, clothes dryers, fluorescent lights, LED lights, or garage door openers.Įlectrical interference may also be caused by power lines. ![]() In the presence of electrical interference, you may experience frozen images or intermittent audio while viewing over-the-air television programs. If you are experiencing interference on your cordless phone, you should contact the equipment manufacturer for assistance. If this is the case, you may be able to verify the interference source if you see an antenna mounted on a nearby house or car.Ĭordless telephones use radio frequencies and have no protection from interference. If your equipment is reacting to nearby transmitters such as an amateur radio or CB installation, you will have interference only when the radio operator is talking and you might be able to hear only half of the conversation. To determine whether the interference is caused by a transmitter or electrical equipment, unplug one household electrical device at a time to see if you can isolate the source of interference. Transmitter interferenceĬommunication systems that transmit signals capable of generating interference include amateur radios, CBs and radio and television stations.ĭesign flaws such as insufficient filtering, inadequate shielding, or frayed or corroded wires may make equipment susceptible to transmitter interference. The two most common causes of interference are transmitters and electrical equipment. Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment. ![]() ![]() Interference occurs when unwanted radio frequency signals disrupt the use of your television, radio or cordless telephone.
