Repellent sounds and noises against birds - 2 hours of loud ultrasonic sound

[@angelinelok2005]

Is it normal if Idon't hear anything as human being?

[@jorgosagb]

Birds can hear up to 8kHz, so ultrasonic sounds (which almost noboday can play because most amps and speakers go to 20kHz) isn't hoing to do anything. Pigeons can hear uktra low frequencies around 0.5 Hz, which would work but, good luck finding the equipment to play these frequencies! Oh, and a miracle apparently happened. I can suddenly hear ultrasonic sound, while up untill I found this video, I could only hear around 15 to 16 kHz. And all of that through the speakers of an S21😄
