As a construction worker myself I have to say - I see lots of problems with this. Sure, it’s great in a relatively quiet situations, but if you’re doing something really loud like working with an angle grinder... that “unnatural” beep really stands out, the hissing of the white noise - not quite. <br>This seems more like a case of “we can sacrifice limbs &amp; lifes of a few more workers just so the fancy people sitting at their homes the whole day wouldn’t be so inconvenienced”
