  • Filter monitoring using differential acoustic attenuation
    Patent number: 12517093
    Abstract: An acoustic monitoring system for detecting a condition of an air filter, the acoustic monitoring system including: a first acoustic transducer upstream with respect to airflow over the air filter; a second acoustic transducer upstream with respect to airflow over the air filter; a third acoustic transducer downstream with respect to airflow over the air filter; a fourth acoustic transducer downstream with respect to airflow over the air filter; a control unit in communication with the first acoustic transducer, the second acoustic transducer, the third acoustic transducer and the fourth acoustic transducer; the control unit configured to determine a filter attenuation value in response to one or more SPL values measured by at least one of the first acoustic transducer, the second acoustic transducer, the third acoustic transducer and the fourth acoustic transducer.
