Why do my speakers make a hissing sound?

Though some noise is inherent in the audio signal (tape hiss, amp gain, etc.), speaker hum and hiss generally come from poor wiring, ground loops or other electromagnetic interferences (AC line hum; RF interference, and USB and PC noise). To rid of the noise, we must rid of the interference.

Why is there white noise coming from my speakers?

White noise is most often caused by the gain, or amplification, turned up too high at some point, either on the monitor, from within software, or from the audio interface. Check the levels of your interface, software, and speakers to make sure that nothing is being over-amplified.

What frequency is audio hiss?

Electromagnetic hiss is a naturally occurring Extremely Low Frequency/Very Low Frequency electromagnetic wave (i.e., 300 Hz – 10 kHz) that is generated in the plasma of either the Earth’s ionosphere or magnetosphere.

What causes amplifier hiss?

Usually it’s the electronic engineering of the amplifier that is responsible for causing loudspeaker interference. When the hissing is so loud that it effects the listening experience then something’s has to be done. Damaged cables or plugs could be causing the unwanted noise.

Why are my car speakers hissing?

If you hear a hissing sound, turn down the gain on the amplifier and turn up the volume on the receiver. Adjust these two settings to minimize the hiss. Make sure the patch cables between the amplifier and the receiver are not running near other power wires (including the wire providing power to the amplifier).

What causes static in stereo speakers?

Sometimes the static in your speakers isn’t static at all, but an electrical grounding problem. The so-called “ground loop hum” or “60-cycle hum” happens when the components aren’t properly grounded. In a car stereo, you may need to use a shorter or heavier ground wire.

Is it normal for an amp to hiss?

Hissing guitar amps is normal. There are things you can do to reduce it, but eliminating it is not something you can expect. Are you using single coil pickups or Humbuckers? Sometimes the culprit is the power supply to the house/room you are playing in.

Do all amps hiss?

Hiss (noise) is normal for all active amplifiers to produce, and is usually audible with ears pressed against the speakers and no signal.

Why does my amp make a high pitched noise?

The higher pitched and more irritating ‘buzz’ is typically found emanating from the loudspeakers and is usually caused by a ground loop. The most common cause of hum is the ground loop – fortunately it is also the easiest to solve.

Why does my stereo make a whining noise?

One common cause of speaker whine comes from the vehicle’s alternator. If the noise changes in pitch or intensity when the engine RPM changes, it’s probably some type of engine noise, and interference from the alternator output is a likely source.

Is your audio gear hissing?

All audio gear has some degree of HISS. You just may not hear it until you turn it up loud enough. As always, we can test for where hiss comes from. Is it: radiated noise (comes through the air into your ax pickups). . Hiss is most often conducted noise. But still, it doesn’t hurt to make sure. How do you decide which it is? The solution is easy:

Why does my preamp Hiss?

All preamps (and all audio gear) hiss. This is called “thermal noise.” If you have the treble control cranked up the hiss will be louder because it has a lot of high frequency energy. Same if you have the treble cranked up on the amp.

What causes background hissing in speakers?

What causes background hissing in speakers though? Essentially, it happens when the electrons stray off the path of their intention due to heat. They’re like little gremlins, causing the output signal voltage to change and create an audible noise that we perceive as a hiss, particularly when the quality of the equipment is low.

Why does my treble hiss when I turn it up?

It is common for active systems to have a bit of hiss when highs are boosted a lot. So if treble is turned way up you normally do get some hiss. But hiss with volume and tone controls having no effect is definitely WRONG. This implies that whatever is driving the cable (post-EQ) is having a hissy-fit.
