Inverse Prediction of Sound Insulation to a Wall with Apertures

With concerning a wall with apertures, which means there exists sound leak, the sound insulation of the wall is impaired severely. Under the meeting of the insulation requirement, inverse sound insulation prediction approach can be utilized to determine the minimum insulation of the solid wall and maximum area of apertures or cracks. The prediction, therefore, will provide the guidance to obtain the allowable value of aperture area for installation of ducts and electrical outlet box on the wall.
