who remembers when you could tell if someone left the tv on the moment you walked into the house?,(reply>), And switching power supplies! OMG they drive me crazy sometimes! (Nowadays we're surrounded by them, so even though I still hear them, they just mesh in the "background noise" so I don't notice it on a day-to-day basis. But there's always a reaaly LOUD one smh :/ ),(reply>), @Mad and Balding litterarly like less than 50% of people wathcing this video mate,(reply>), everyone. they didnt stop making tvs with speakers.,(reply>), me,(reply>), I can still tell now, even with my fancy flat screen! Actually, I can generally tell if anything is on, like an alarm clock or a wireless charger. I kid you not, they all make a certain noise and I can distinctly hear them. They actually keep me up at night sometimes!
