Abstract: 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.

Abstract: Systems and devices may receive an ambient noise signal and use that ambient noise signal to generate a distorted ambient noise signal that may be provided to a speaker that is proximate to a microphone of the audio-activated device so that the speaker may project sound corresponding to the distorted ambient noise into the microphone of the audio-activated device so that, for example, that the audio-activated device cannot decipher speech and other sounds in the ambient noise of an environment. While the distorted ambient noise is being projected into the microphone of the audio-activated device, it may be scanned and/or analyzed to determine whether an audio trigger (e.g., an audio trigger or phrase) is included therein and, if so, an undistorted ambient noise signal may be communicated to the speaker of the audio-activated device so that the audio-activated device may respond to a command included in the ambient noise.
