A pressure relief assembly (100) includes a housing (102) including an air passage chamber (104) having a flap barrier (122) surrounding at least one airflow passage. A membrane flap is secured within the air passage chamber. The membrane flap covers the airflow passage(s) in a closed position. A portion of the membrane flap is configured to move off the airflow passage(s) into an open position. A noise-dampening seal (120) formed of a noise-dampening material is proximate to at least a portion of the flap barrier. The noise-dampening seal is configured to reduce noise generated by movement of the membrane flap as the membrane flap moves from the open position to the closed position. The noise-dampening seal provides a sealing interface with the membrane flap in the closed position.
