1. A method comprising:
- receiving first ambient sound information from a mobile device;
receiving reference ambient sound information from each of a plurality of reference devices, the reference ambient sound information including first reference ambient sound information received from a first reference device of the plurality of reference devices and further including second reference ambient sound information received from a second reference device of the plurality of reference devices;
determining degrees of similarity, the degrees of similarity including a first degree of similarity between the first ambient sound information and the first reference ambient sound information and further including a second degree of similarity between the first ambient sound information and the second reference ambient sound information; and
in response to determining that the first degree of similarity is greater than the second degree of similarity, estimating a location of the mobile device based on a location of the first reference device.

Abstract
A method for determining a location of a mobile device with reference to locations of a plurality of reference devices is disclosed. The mobile device receives ambient sound and provides ambient sound information to a server. Each reference device receives ambient sound and provides ambient sound information to the server. The ambient sound information includes a sound signature extracted from the ambient sound. The server determines a degree of similarity of the ambient sound information between the mobile device and each of the plurality of reference devices. The server determines the location of the mobile device to be a location of a reference device having the greatest degree of similarity.
