Predict transmission loss, impact sound, and rain noise
INSUL is a program for predicting the sound insulation of walls, floors, roofs, ceilings and windows. Impact sound and rain noise of floors and roof. The programme can make good estimates of the Transmission Loss (TL) or Impact Sound (Ln) in 1/3 octave bands and Weighted Sound Reduction Index (STC or Rw) or Impact Rating (IIC/LnTw) for use in noise transfer calculations or acoustical design or specification.
