Control effects on radiated sound

The aim of this page is to illustrate the experimental results shown in the submitted paper entitled: « Mode Tuning of a Simpli ed String Instrument Using Time-Dimensionless State-Derivative Control order actavis promethazine codeine « . Recordings matching the measured sounds of section « 3.4 Modification of the Simplified Instrument’s Sound » can be listened to. The first recording reflects the radiated sound of the uncontrolled soundboard and the other is the radiated sound of the controlled soundboard. The spectrograms of the sounds are given for comparison with the recordings in both cases.

Recording of the sound radiated by the uncontrolled soundboard excited by a struck string:
