Start with your device volume low. Very low tones may be inaudible on phone or laptop speakers; very high tones can be uncomfortable on headphones.
What does 44 Hz sound like?
44 Hz is a sub-bass frequency. It is a very deep sub-bass tone that you feel in your chest as much as hear. Small speakers struggle to reproduce it; good headphones or a subwoofer will.
A 44 Hz sound wave completes 44 cycles every second, so one cycle lasts 22.7 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 7.80 m (25.58 ft) long; in water it stretches to 33.66 m because sound moves about 4.3 times faster there.
Musically, 44 Hz is 14 cents above F1 (43.65 Hz) in standard A440 tuning. Doubling it to 88 Hz raises the pitch by one octave; halving it to 22 Hz lowers it by one.
