Disclosed herein is a sound synthesis system for generating a user defined synthesised sound effect, the system comprising: a receiver of user defined inputs for defining a sound effect; a generator of control parameters in dependence on the received user defined inputs; a plurality of sound effect objects, wherein each sound effect object is arranged to generate a different class of sound and each sound effect object comprises a sound synthesis model arranged to generate a sound in dependence on one or more of the control parameters; a plurality of audio effect objects, wherein each audio effect object is arranged to receive a sound from one or more sound effect objects and/or one or more other audio effect objects, process the received sound in dependence on one or more of the control parameters and output the processed sound; a scene creation function arranged to receive sound output from one or more sound effect objects and/or audio effect objects and to generate a synthesised sound effect in dependence on the received sound; and an audio routing function arranged to determine the arrangement of audio effect objects, sound effect objects and scene creation function such that one or more sounds received by the scene creation function are dependent on the audio routing function; wherein the determined arrangement of audio effect objects, sound effect objects and the scene creation function by the audio routing function is dependent on the user defined inputs.

An unmanned aerial vehicle (UAV) may emit masking sounds during operation of the UAV to mask other sounds generated by the UAV during operation. The UAV may be used to deliver items to a residence or other location associated with a customer. The UAV may emit sounds that mask the conventional sounds generated by the propellers and/or motors to cause the UAV to emit sounds that are pleasing to bystanders or do not annoy the bystanders. The UAV may emit sounds using speakers or other sound generating devices, such as fins, reeds, whistles, or other devices which may cause sound to be emitted from the UAV. Noise canceling algorithms may be used to cancel at least some of the conventional noise generated by operation of the UAV using inverted sounds, while additional sound may be emitted by the UAV, which may not be subject to noise cancelation.

A mental targeting system. The mental targeting system has a housing which includes a base, at least one sidewall extending from the base, and a top surface, all of which defines an interior volume. A control circuit is disposed in the interior volume which is in electrical communication with a speaker, a microphone, a projector, a plurality of buttons, and a non-transitory computer readable medium. The speaker is disposed in a sidewall and plays sounds stored in the non-transitory computer readable medium. The projector includes a projection lens, and is disposed on the top of the housing where it projects light through a removably securable disc. A slot disposed in the sidewall below the projection lens is used to deposit and retrieve the disc. Full insertion of the disc into the slot positions a portion of the disc directly below, and parallel with, the projection lens.

An imaging device includes an image sensor, a controller, and an annunciator. The image sensor is configured to capture an object image entering via an optical system. The controller is configured to control focusing operation to focus the object image by the optical system. The annunciator is configured to output focusing sound that has a predetermined frequency characteristic according to the focusing operation. The frequency characteristic of the focusing sound includes a first sound component based on first frequency, and a second sound component based on second frequency that is higher than the first frequency and lower than twice frequency of the first frequency.
