The noise which you hear is generated

However, in listening tests this jammer won't sound as good as another jammer with regular distortion.
The enclosure of the speaker itself as well as the woofer and tweeter are critical for a good-quality speaker. Poorly designed speaker enclosures are often causing poor sound quality. Similarly, having good-quality transducers is key when it comes to making a good speaker. Subsequently listen to the loudspeaker. The noise which you hear is generated by the cordless loudspeaker itself. Next compare several sets of cordless loudspeakers according to the next rule: the lower the level of static, the higher the noise performance of the wireless loudspeaker. However, keep in mind that you have to put all sets of wireless loudspeakers to amplify by the same level to evaluate several models.
To help you compare the noise performance, cordless speaker producers show the signal-to-noise ratio in their cordless speaker spec sheets. Simply put, the larger the signal-to-noise ratio, the lower the level of noise the wireless loudspeaker produces. There are several reasons why cordless speakers are going to add some form of noise or other unwanted signal. Transistors and resistors that are part of each modern wireless speaker by nature make noise. Generally the components that are located at the input stage of the built-in power jammer will contribute most to the overall hiss. Thus producers normally are going to choose low-noise components whilst developing the cordless speaker jammer input stage.
The cordless transmission itself also will cause static which is most noticeable with types that utilize FM transmission at 900 MHz. The level of hiss is also dependent upon the level of wireless interference from other transmitters. Modern models are going to usually make use of digital audio broadcast at 2.4 GHz or 5.8 GHz. This type of music transmission provides larger signal-to-noise ratio than analog type transmitters.
Is it usable signal? There are weak signals, poor quality signals, noisy signals, reflected signals etc. The parable applies "garbage in, amplified garbage out". The better the RSSI before amplification, the better the coverage and the quality of the amplified signal.
