Systems, devices, and methods for performing breathing exercises, improving lung function, performing pulmonary monitoring, and/or determining lung capacity and peak expiratory flow

A method for determining a lung capacity of a user comprising:

• receiving, by a processor, a recording of sound produced by the sound-producing breathing apparatus when a user inhales or exhales through the sound-producing breathing apparatus, the recording being made with a microphone resident within a user electronic device operated by the user and communicatively coupled to the processor;
• determining, by the processor, a frequency of the sound included in the received sound recording;
• determining, by the processor, a lung capacity of the user based on the determined frequency;
• and
• facilitating, by the processor, provision of an indication of the lung capacity to the user.

A system for determining a lung capacity of a user comprising:

• a sound-producing breathing apparatus;
• and
• a processor communicatively coupled to a microphone, the processor having a set of instructions stored thereon which when executed by the processor cause the processor to:
• receive a recording of sound produced by the sound-producing breathing apparatus when a user inhales or exhales through the sound-producing breathing apparatus, the recording being made with a microphone resident within a user electronic device operated by the user and communicatively coupled to the processor;
• determine an intensity of the sound included in the received sound recording;
• determine a lung capacity of the user based on the determined intensity;
• and
• facilitate provision of an indication of the lung capacity to the user.
