On the other hand, if your only problem is with the wiring of the amplifier or unsuitable cables, the hissing should all but disappear when you use them to play music. Therefore, taking care of visible physical damage on the speaker should take precedence. Hearing a hissing sound when your speakers aren’t playing music shouldn’t affect audio reproduction, but a blown speaker will. So if you’re continuously hearing a hissing sound whether the speakers are playing music or not, consider that there are multiple issues you need to address. That could make troubleshooting the problem you’re currently dealing with more difficult than it needs to be. #Speaker hiss crack#If there’s a crack in one of the external parts of the speaker, such as the dust cap, the diaphragm, or the rubber surround, playing music would make the speakers produce a hissing noise. Moreover, they might conceal the underlying cause of the noise you hear when the music isn’t playing.įor example, a blown speaker typically wouldn’t cause noise without audio input. Namely, physical damage could make the hissing louder when the speakers are in use. However, there are other factors that could be making the noise worse. Potential Contributing FactorsĪt this point, you know everything that might cause speakers to produce a low hissing sound when they’re not playing music. Balanced cables have an additional wire that carries the signal with a negative polarity, canceling out background noise and interference. Well, unbalanced cables only have two wires inside them - one carries the audio signal while the other is a ground wire that protects against interference. If it has two rings (like a TRS cable), it’ll have a balanced signal. If it only has one black ring, it’s unbalanced. Once again, you should be able to tell by simply looking at the jack. Quarter-inch instrument cables and 3.5 mm aux cords can also be unbalanced. If the audio input cable is connected to an RCA port, it’s probably unbalanced - those red and white audio cables usually are. #Speaker hiss professional#If you have professional audio monitors (which are more susceptible to this kind of noise), you’ll find several ports in the back of the speaker. You can always perform a visual inspection to confirm these findings. If the sound volume decreases after you’ve eliminated these variables, your speakers are probably using unbalanced cords. So if you have a bunch of them lying around, you might want to separate them. In fact, different unbalanced cables could even trigger each other. Electronic devices like computers and Wi-Fi modems could have the same effect. Of course, phones aren’t the only things around that might have a magnetic field that’s strong enough to cause interference. It’s not because of you, though - more likely, the culprit is the phone in your pocket. That means that the hissing sound would become worse when you approach your speakers. If the unbalanced audio cables are the underlying problem here, the issue may be exacerbated by electromagnetic interference. Alternatively, you could downgrade to a cheap speaker set that probably won’t make the detestable hissing sound. #Speaker hiss upgrade#If yours don’t have that, you’ll have to upgrade to pricier audio monitors. You just need speakers that have individual ports for different kinds of cables. It’s somewhat of a non-issue, though you may be able to eliminate the sound with minimal intervention.Īs for the other two potential causes, you’ll be happy to learn that the cords in question are easy to replace. Thermal noise is a fairly standard occurrence that you’ll have to live with. If your speakers have built-in amplifiers, you probably won’t be able to get rid of the hissing sound. Grounding issues in the power supply cord.The electronic circuit in the speaker’s amplifier.If the hissing sound has a structural cause, it’ll be in: But let’s clarify how wiring can cause speakers to act out like this. In any case, you already know the short and admittedly vague answer to your question today. With that in mind, I can only encourage you to read my explanation of why some speakers buzz if you don’t find your answers here. Sure, tapping and clicking are easy enough to detect, but buzzing and hissing sounds are fairly similar. Speakers can make a wide variety of unwanted sounds that aren’t always easy to describe.
