Abstract: Apparatuses and methods for improved noise reduction and voice capture in respiratory protective devices are provided. For example, an example respiratory protective device includes at least one fan component secured to the respiratory protective device, at least one sound sensor component positioned within the respiratory protective device and generating a detected sound signal, and a controller component electronically coupled to the at least one fan component. In some examples, the controller component is configured to receive a detected fan speed signal, retrieve a corresponding noise profile data object, generate a noise-reduced sound signal, and transmit the noise-reduced sound signal to a data communication component.
