Unfortunately for me the workers are in the house. I bought these parts in stores where a saleswoman me
persuaded that a similar attenuation as the Laser Lite can be expected (from Howard Leight Industries).
This statement was sadly mistaken, because you all ambient noise only slightly damped can perceive. The damping is
at SleepSoft about 18 dB, with the Laser Lite about 35 dB. Compared to the laser Lite are the SleepSoft in
Noise reduction similar to cotton, which has proven itself at concerts (where you still want what fortuitous).
Currently the Laserlite are in a 200-pair bulk pack for about 29, - Euro to have,
commercially house from 1, - Euro per pair.
