Methods and modules are provided to enable measurement of ambience parameters using audio signals emitted and received by a user' s cellphone.
The cellphone speaker is configured to emit signal(s) of specific sound pattern(s), which may be in the audible range and/or in the ultrasonic range, and comprise one or multiple sounds at different intensities and pitches.
The cellphone microphone is configured to remain receptible during the operation of the speaker, in contrast to the usual configuration of preventing reception by the microphone of speaker- originated sounds to avoid creating acoustic feedback.
The speaker-emitted signal is received by the microphone, and analyzed with respect to the emitted signal, to derive corresponding ambience parameters such as temperature, relative humidity, air pressure, air quality etc. from measurements of the speed of sound of different signal components, such as different frequencies and intensities. A schematic illustration of the system is presented below.
The analysis may be supported by a preliminary empirical study relating a variety of ambience parameters to measurements of the speed of sound under the corresponding conditions, carried out e.g., along lines similar to those described in Astura et al. 2014 ("Air temperature measurements based on the speed of sound to compensate long distance interferometric measurements", EPJ Web of Conferences 77, 00013, DOI: 10.1051/epjconf 20147700013).

The cellphone may deliver and receive data from a cloud service, and possible carry out some or all calculations on the cloud. Experimental data may be enhanced by measurements carried out on cellphones which have independent sensors for measuring ambience parameters. Calibration stages by the user may refine the results and/or enable initial calibration of the system. A monitoring unit may be configured to receive the measurement data from many cellphones and
analyze environmental and atmospheric conditions over a geographic range in which users are located, to yield cumulative data aggregation.
