How Quiet Is a TV Lift Cabinet Motor?

One of the first things people want to know when considering a TV lift cabinet is: "Is it going to sound like a garage door opening in my bedroom?" The answer, for quality cabinets, is emphatically no.

The Sound Profile of a Good Lift Motor

Quality TV lift mechanisms use DC brushless motors paired with precision lead screws or column drives. These create a smooth, low-frequency hum — not a whirring, grinding, or clanking sound. The travel time from fully closed to fully raised typically takes 8 to 15 seconds depending on the mechanism, and during that time the sound is constant and subdued.

At 35–45 dB, you're hearing something quieter than a running refrigerator and far quieter than a conversation. In a bedroom at night, you'll hear it — but it won't startle you or anyone else in the room.

What Makes a Lift Mechanism Louder?

The main culprits in noisy lift cabinets are:

• Brushed DC motors — older technology, more friction, more noise
• Loose mechanical tolerances — cheap manufacturing allows
