Delivery sound masking and sound emission
First Claim
1. An unmanned aerial vehicle (UAV), comprising:
- a propulsion system including propulsion units that include at least;
a propeller; and
a motor;
a speaker;
one or more processors; and
memory storing computer-executable instructions that, when executed, cause the one or more processors to;
determine a first stage of a flight to deliver a package to a destination associated with a customer;
cause the speaker to emit a first sound during the first stage of flight that masks at least part of noise generated from operation of the motor and rotation of the propeller;
determine a second sound to be emitted by the UAV, the second sound associated with a preference of the customer;
determine that the UAV is executing an approach to the destination or executing a landing at the destination; and
cause the speaker to emit the second sound during the approach, during the landing, or both.

Abstract
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.

7. A method, comprising:
-
determining a flight plan to cause an unmanned aerial vehicle (UAV) to execute a flight to deliver a package to a destination associated with a customer; selecting a sound stored in a storage device to be emitted by the UAV during the flight, the sound to mask at least part of noise generated from operation of UAV; and causing a speaker to emit the sound during at least a portion of the flight. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A system comprising:
-
one or more processors; and memory storing computer-executable instructions that, when executed, cause the one or more processors to; determine a destination for delivery of a package by an unmanned aerial vehicle (UAV) select a sound, stored in a storage device, to be emitted by the UAV during at least a portion of the delivery to the destination, the sound to mask at least part of noise generated from operation of UAV; and cause a speaker to emit the sound during at least a portion of the delivery. - View Dependent Claims (17, 18, 19, 20)
