Abstract
Embodiments relate generally to devices and methods for improved active noise cancellation hearing protection. For example, multiple speakers might be used in each earcup, with each speaker providing active noise cancellation for a narrow frequency range which is a portion of the total frequency range of the entire array of speakers. By dividing the active noise cancellation up across an array of speakers, each speaker can better target its specific narrow frequency range, resulting in improved active noise cancellation.
