Different embodiments of methods and apparatus to produce audio output signals are disclosed. In one embodiment, an ultrasonic speaker outputting ultrasonic signals can be transformed into first audio output signals, which are directional. A non-ultrasonic speaker can output second audio output signals. The embodiment can be configured to output the first audio output signals or the second audio output signals in a vehicle. Another embodiment can be configured to output the first and the second audio output signals together. Yet another embodiment can be configured to be personalized to hearing characteristics of a user, or to depend on sound level of an environment of the user. One embodiment can include a directional speaker attached to a vehicle, with its output steerable towards a user in the vehicle.
