Why does a CD crackle—and when is that normal?

A slight crackle is part of the vinyl sound—something many people even come to love. But there’s a point beyond which the crackling signals that something needs to be fixed.

When Is a Clicking Sound Normal?

A faint, soft click between songs or at the beginning of a record is usually just a characteristic of the analog format—tiny specks of dust in the groove, fingerprints, static electricity, or the very structure of the record itself.

When Should You Be Concerned?

If the rattling is constant, loud, or occurs in the same places every time, the likely cause is dirt in the groove or scratches on the surface.

• – Dust and static electricity – the most common cause, addressed with an antistatic brush before each hearing
• – To avoid leaving grease marks from your fingers, hold the disc only by the edge and the label
• – Dirt that has accumulated in the groove – requires deeper with cleaning fluid
• – A worn or dirty needle can scratch the record itself

 

The best way to ensure clear sound is to clean your records daily with an antistatic brush. This should become a habit: cleaned records will not only last longer but also sound cleaner, which will also extend the life of the stylus. You can find more care tips on our Disc Care in the category.

A Simple Solution for Your Home

Wipe the disc before each playback AM antistatic brush – Its nearly 600,000 carbon fibers remove dust and static electricity in a single pass. If the disc hasn’t been cleaned in a long time or was purchased used, it’s worth giving it a deeper clean with a special cleaner—it gently removes even stubborn dirt.

If the rattling doesn't go away even after cleaning, check the needle—it may be time to replace it.

Broken needle

A worn-out stylus is the most common—but least recognized—cause of poor sound quality. Every stylus has a certain lifespan during which it naturally wears out. This doesn’t mean you need to keep track of how many hours you listen to music—the best way to protect your turntable is to replace the stylus preventatively every one to two years, or every three years if you listen less frequently. Proper cleaning of the stylus with a special cleaner or brush helps extend its lifespan.

But even with careful handling, the needle can be damaged very easily by mechanical force. If you accidentally press down on, bump, or drop the needle, you can not only break it but also damage it—and it’s not easy to spot damage on a microscopic diamond tip. Therefore, it’s best to replace the needle as a precaution, even if you haven’t yet heard any obvious signs of wear.
