摘要：
Systems, devices, and methods for determining a user's lung capacity may employ a sound-producing breathing device and a recording device such as a microphone included in a user electronic device (e.g., smart phone or tablet computer). A user may inhale or exhale through the sound-producing breathing device, thereby producing a sound that is received by the microphone and communicated to a processor. The processor may analyze the received sound recording to determine one or more sound intensity values over, for example, the duration of the received sound and/or points in time within the sound recording. The sound intensity values may then be used to determine the user's lung capacity.
