Why is it not possible to jump over a Sound Level Meter?

Several people were asked to jump over an XL2 placed on the floor, but none of them could do it. Why?

In physics it is enough that the audible wave be produced; "sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as air, water or other materials."


In human physiology and psychology sound does not exist unless a brain receives it; "sound is the reception of such waves and their perception by the brain." -


The XL2 was placed in a corner on the floor. Therefore, it is not possible for a person to jump over it.

- Paul Sinclair, NTi Audio

they were on level 1 floor and the XL2 was on level 2 floor .....  - Bob W.

They couldn't jump over the XL2 because it is a thing of beauty, and they had to get closer to admire it ;) - Kevin H.

Could it be because landing on the floor from a jump might excite the floor to generate low-frequency signals that would exceed the 5 Hz frequency limit of the NTi microphone?


Alternately, the jumpers were from the Swiss Olympic ski team and could not manage such a high jump!! - Neil S.

They afraid to damage unit? :) - Jan P.

too nice to be destroyed ! - Gianni P.

it was placed against a wall or in a corner - Peter P.

Is it because the plastic bits break under the force of a light breeze? - Adam M.

Because they are fond of the XL2. - Andrea T.
