How loud is a blender?

1. LOUD!

 Most blenders come with a built-in sound suppressor that reduces noise from the motor. But if your blender has no sound suppressors, then the motor can create loud noises ranging from 67 decibels (dB) down to 45 dB. This is the same level of sound as running a car engine at 100 miles per hour.

If you want to know how loud a blender is, try this experiment. First, place your hand over the top hole of the blender lid. Second, then slowly turn the speed dial until you reach the highest setting. You should feel some vibration through your palm.

 2. NOT SO LOUD!

 It may surprise you, but many blenders are much quieter than those listed above. Here’s how to tell. Start the blender, and hold a piece of paper or cardboard directly against the side of the lid just below the blade. Slowly increase the speed until the paper vibrates.

As the speed increases, the paper will start to move back and forth faster and faster. When the paper starts moving back and forth too fast to read, the blender speed is somewhere between 5,000 RPM and 6,000 RPM. At these speeds, the blades are creating vibrations between 30 dBA and 35 dBA.
