Audibility -

: The standard human hearing range spans from 20 Hz to 20,000 Hz . Sound falling outside this range—such as infrasound or ultrasound—lacks audibility for humans.

: Sound intensity decreases as it travels away from the source, making distant sounds harder to hear. audibility

: High ambient noise masks quieter sounds, reducing their audibility. : The standard human hearing range spans from

: Louder sounds have higher intensity, making them more likely to cross the audibility threshold. audibility
