Most helmets do not integrate electronics or sound. Instead, they contain small recessed areas behind the lining for you to put two speakers that attach to your choice of sound system (e.g. a bluetooth headset with mesh intercom). This is a simple way to divide the expertise between two firms who specialize in different things. Integrating noise-cancelling electronics into the product itself is not this simple. Bell Helmets doesn't employ firmware engineers.
