Acoustic uroflowmetry, also known as microphone-based uroflowmetry, is a newer method of measuring urinary flow. A phone or another microphone listens to the sound of urination. Special software then uses the audio recording to estimate parameters such as maximum urinary flow rate, average flow rate, voiding time and voided volume. Because this method uses a… Continue reading Is Acoustic Microphone-Based Uroflowmetry Safe? A Comparison with Conventional Uroflowmetry.
