Description
This file features the 55 Hz A1 Pure Sine Wave, a genuine low-frequency bass note in the key of A.
This tone is ideal for listening along with music or enjoyed all by itself. The 55 Hz A1 is notable as one of the few low musical frequencies that does not require a decimal point in the 440 Hz A-centered equal temperament scale. For the best experience, headphones or large speakers are highly recommended.
Small speakers, such as those in phones, tablets, and laptops, are generally not as capable of accurately delivering these long wavelengths and typically cut off the lows around 60 Hz to 80 Hz to minimize damage.
