What Causes Speaker Hum & Hiss (How To Eliminate Them Both)


So annoying! A humming or buzzing noise can really wreck your vinyl experience, so let's go through some troubleshooting steps to try and figure out where it's coming from. It's important to note that some humming is a reality of analogue gear — if you're only hearing the hum when you've got the volume cranked up to 88, then it's within normal range. If you're at a more normal listening level and still getting hum, then we've got work to do! Firstly, does the sound come through to the speakers?

You can test that by turning up the volume with nothing playing, and if you hear the buzz get louder, it's carrying through to your speakers. If it doesn't get louder, it'd most likely motor rumble or something physical going on with your turntable.

Jump ahead a few steps in that case. If the sound's coming through the speakers, the next step is to figure out its origin. Try playing through your stereo from a source other than your turntable — if the problem is the same playing off your phone or a CD, the issue is somewhere else in your system. Have a look at your amplifier or the speakers themselves, and contact the manufacturer if you can't get to the bottom of the issue.

Once you've narrowed it down to the turntable, we need to figure out what kind of hum you're dealing with. The most common noise is a grounding hum. Check out the beginning of this video for an example of the common ground hum. Pro-Ject turntables come with phono cables that have small attachment called a grounding spade , also known as a grounding fork see the picture below , to fix this exact issue.

That grounding spade should be connected to the grounding pin on the turntable, which is typically between the RCA connections on Pro-Ject turntables see picture below. Then the other end of the phono cable will be plugged into a phono stage or an amplifier, each of which should have their own grounding pin. With the phono cable connected to grounding pins on both ends, the grounding hum should be sorted.

If it persists, though, there are a number of factors that can be in play — some are to do with the turntable, others to do with the space the turntable is in. Let's try and rule out a few other factors. Over time, they may work loose, and an open channel can cause a humming noise similar to the ground hum.

Be very careful when checking tonearm wires, and they're quite delicate. If one is loose, you can slide it back onto the pin in the back of the cartridge using needle-nosed pliers and a gentle rocking motion. The sensitive stylus in your cartridge can pick up vibrations from other equipment, which can cause buzzing or humming sounds. Electrical interference from nearby wiring, or household appliances like computers, fridges etc, can get picked up and added to the sound coming from your speakers.

In that case, we recommend using an IsoTek IsoPlug, or one of IsoTek's power boards, to help isolate your stereo system from power noise. If you've got a phono cable with the grounding pin, that's better, but a generic RCA cable will still help for troubleshooting. Test the connection with a new cable, and see if the sound changes. Then the noise is probably caused by something moving around in a way it shouldn't; most commonly, the motor is the root of that issue.

On models in the Debut and Xpression series, the motor ships secured with two transport screws in the two holes on either side of the motor see picture below. Underneath each of those 'wings', there should be a small black dome supporting the motor to help prevent its vibrations from carrying through to the rest of the turntable.

If you've got those domes and the transport screws that came with the turntable, we recommend keeping those screwed in part-way to keep the motor nice and stable.

No need to screw them all the way in, as that'll defeat the purpose of the domes — just enough that they keep the motor from rocking when in use. If you don't have those spare parts, or your turntable didn't come with them, you can order a Turntable Modification Kit for Debut models.

Why Is My Speaker Making Noise When Car Is Off?

Hello everyone, this is my first post on this forum. This is also my first project using any sort of Arduino controller. I am currently following a guide for building a lightsaber based on an Arduino Nano. Everything seems to be working fine except for the speaker, which is playing.

Some installed sound systems using CXD amplifiers have exhibited audible high-frequency noise in the loudspeakers when at idle (no signal.

How to Remove a Humming or Hissing Sound from Speakers


Did you know that even though rare it is not unheard of to hear a static hissing sound or ticks and pops? So, I set out to find the origin of the noise and get rid of it. The noises coming from your speaker may sound like white noise, static noise hissing , popping, etc. The issue with isolating the source is that any component that creates an electrical field from the windshield wiper motor to even the speaker wires may be the culprit in this case. The key is in identifying where the noise is coming from, which is not an easy task. Unless you are a professional and have know-how on tinkering with the wiring, you might not want to try this yourself. Some vehicles are designed with the radio and speaker system having constant access to power at all times. In this case, your speaker might make noises even when your car is off with the keys removed. This is the first thing you should check in your car.

These vibrations can pre-exist in the instrument, particularly if it's made out of wood, or they may only appear when the instrument is amplified.

Buzzing from one speaker in 5.1 setup


Hissing or humming sounds are a consequence of concurrent sound waves produced with different frequencies and sound levels, the most common being white noise. In turn, this can cause significant issues in performance, possibly even speaker damage. Audio signals Alternate Current electrical signals are passed through conductive wires, amplified and then delivered to the speakers. When leads or equipment is connected, this electrical signal passes from one component to another. Speakers are transducers that convert electrical energy audio signals into mechanical wave energy sound waves and any interruption to the AC signal will cause this unwanted noise. Speakers are designed to move linearly according to the applied audio signal.

How To Remove Humming Noise From Amplifiers

Googling for audio hardware forums brought this up and it was the only place I recognised and so possibly trusted. It happens even as a standalone unit with just the speakers attached it increases slightly if I put it at full volume. It also reduces if I attached the amp ground to one of the speakers itself. I spoke to a friend last night about it who said it could be an internal grounding issue, unsure how to fix it though. I can take photos of it if need be and appreciate any help with this. Sounds to me like a power issue, possible issue with the transformator power supply Or other bad components in the power cirquit. My dad had a similar issue with a Harman Kardon amp in the past. The humming noises in that were caused by a bad trafo.

Non-Alternator Engine Noise Problems. If you have an external amplifier, you can pick up other engine noises that don't have to do.

Clipping, buzzing and humming are the most common forms of unwanted noise caused by sound distortion. All of these noises are often related to the amplifier. If you have experienced any of these noises, you are one among many audio enthusiasts seeking answers to the question:.

So, I recently swapped a 4 zone matrix amp out for an 8 zone amp non-matrix amp and a 16 zone audio matrix. My audio now consists of the audio matrix, the 8 zone amp and an 8 zone matrix amp. Connections go to the matrix, then the matrix outputs go to the amps and then obviously the speakers are hooked to the rooms. All the rooms that are hooked up to the 8 zone, non-matrix amp, BUZZ The only way to stop the buzzing is to turn off the amp.

Kenwood KA Amplifier Buzzing. Greetings, I have a Kenwood KA amplifier. It emits an incredibly loud buzzing sound when the power switch is turned on. The buzz is coming from an electromagnetic switch on the same circuit board as the fuses. The electromagnet doesn't seem to be generating enough force to hold the moving part of the actuator still.

But what actually causes this annoying problem? It can be a bit of work solving this mystery, but read on as we try to show you how to find the cause of your loudspeaker interference. These annoying sounds are caused by simultaneous sound waves that are produced with completely different frequencies and sound levels.
