How Loud is the Blender?

We blended ice and water (the loudest thing you can blend) and found the following measurements:

At 2 feet, it peaked at 85db for the first few seconds and fell to 75-80 for the rest of the time.
At 5 ft, it peaked at 77 for the first few seconds and fell to 70-73.
At 7 feet, it peaked at 73 db for the first few seconds and fell to 65-70.
At 10 ft, it peaked at 71.

Db are logarithmic like the Richter scale. 85 is 10 times louder than 75.

You can reduce your noise leak to other booths significantly with some type of barrier like a dividing panel, at ear level.

We can’t say what the noise levels will be when people cheer for each other. Hope this helps!
