Abstract: A cartridge for an aerosol provision system that includes the cartridge and a control unit. The cartridge includes an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region; a heating element for heating aerosolizable material, such as liquid, from a reservoir to generate aerosol in the aerosol generation region; and a valve located in the air channel upstream of the aerosol-generating region. The cartridge is configured such that air passing through the air channel is configured to pass from the air inlet, past the air valve, into the aerosol-generating region, and then out from the aerosol outlet.

Abstract: An apparatus and method for attenuating sound from an engine exhaust. The relative lengths of the expansion chambers and other components within the apparatus provide a quadruple tuning effect which attenuates sound over a wide frequency range. Attenuation at higher frequencies is also increased and extended by the use of acoustically lined internal baffle tubes inside the apparatus housing.
