Abstract
An earpad comprising one or more acoustic resonators coupled to a contact face of the earpad that is configured to interface with a user's head, the acoustic resonators being configured to attenuate leakage of parasitic sound.
Claims20
An earpad, comprising:
- one or more acoustic resonators coupled to a contact face of the earpad that is configured to interface with a user's head, the one or more acoustic resonators being configured to attenuate leakage of parasitic sound, wherein the one or more acoustic resonators are configured to attenuate propagation of parasitic sound based on at least one of a specific acoustic impedance (ZR) of the one or more resonators and a surface porosity (ΦR) due to the one or more resonators, and wherein
- interfaces to the one or more acoustic resonators are located at the contact face of the earpad.
An earpad, comprising:
- one or more acoustic resonators coupled to a contact face of the earpad that is configured to interface with a user's head, the one or more acoustic resonators being configured to attenuate leakage of parasitic sound, wherein
- the one or more acoustic resonators are configured to attenuate propagation of parasitic sound within a predefined target frequency band (F),
- the predefined target frequency band (F) is defined by impedance (ZR) of the one or more resonators, a surface porosity (ΦR) due to the one or more resonators, and a resonance frequency (fR) of the one or more resonators, and
- the earpad comprises a core material and a cover material, the cover material acting as the contact face of the earpad, wherein the cover material is perforated at areas of interfaces of the one or more resonators.

An earpad, comprising:
- one or more acoustic resonators coupled to a contact face of the earpad that is configured to interface with a user's head, the one or more acoustic resonators being configured to attenuate leakage of parasitic sound, wherein
- the one or more resonators are one or more Helmholtz resonators, each Helmholtz resonator among the one or more Helmholtz resonators comprising a mass channel and a compliance cavity,
- the compliance cavities of the one or more Helmholtz Resonators are combined into a joint compliance cavity connected to each of the mass channels of the one or more Helmholtz Resonators, and
- the earpad comprises a plurality sections, each of the sections comprising one joint compliance cavity and a plurality of mass channels connected to the one joint compliance cavity.
