A subjective test study was carried out in order to identify the perceptibility of changes in the Q-factor of room modes. The experimental technique concentrates on the identification of difference limen for three levels of Q-factor referring to modes in rooms used for critical listening. Trends show that changes in higher Q values are more perceptible than those for lower Q values. The results may be applied in decisions for treatment of modes in common listening and control rooms.
