Instead, the sound starts to hiss at high tones.

Meaning that high-quality speakers can’t play at their best. Lossy MP3 files don’t deliver any high-frequency range. Shop now When bad audio files ruin the soundīelieve it or not, but loudspeakers can be “too good” for some audio sources. And just to keep it complicated, the cause could be something completely different. If the noise does move, then you have a hint that the issue could be related to the transducers (sound converters). In the case that the source of the interference doesn’t change then it’s a major sign that the problem is related to the amplifier. Luckily, there’s an easy way to test this, just change the positions of the loudspeakers and see if the position of the unwanted noise moves. Usually, however, the cause is a result of the amplifier. Damaged cables or plugs could be causing the unwanted noise. When the hissing is so loud that it effects the listening experience then something’s has to be done. Usually it’s the electronic engineering of the amplifier that is responsible for causing loudspeaker interference. However, it should not worsen the listening experience. How loud this sounds though, depends on the quality of the sound system. This is often referred to as the signal-to-noise ratio (S/N). Whenever you get up close to the speakers you can always hear a little noise. You can hear it best when you have nothing connected to the amplifier or receiver apart from a loudspeaker and turn the volume down. This is because an amplifier always emits a basic or inherent sound. So, first check either your A/V receiver or amplifier. Instead, it’s the input devices where the cause can be found. Passive sound transducers that are dependent on an input device don’t cause a hum or hiss. It’s important to tell the difference between hissing and humming, as they have different causes and mainly occur in the subwoofer. One of the most well-known is white noise. We can often hear when our speakers hum or hiss, but what’s actually going on? These annoying sounds are caused by simultaneous sound waves that are produced with completely different frequencies and sound levels.
