Device for the Sound Quality Measurement of Reeds

The test device was recently developed and realized, which meets the specific requirements for the reproducible sound quality measurement of reeds. The air flow through the reed with a small negative pressure is controlled by means of pressure sensor in the feedback. The device provides an objective assessment of A-weighted sound pressure level, relative harmonic spectrum, inharmonicity, air consumption and average intake pressure. The evaluated values are stored in the database and are available for further processing and comparison. The measurement is controlled and evaluated by means of PC application. The device functionality is verified by a regular use in R&D and production quality activities.
