I observed from the graph that the example partition exhibits a sound reduction value of approximately 10dB - 15dB at frequencies below 125Hz. What would be considered a suitable sound reduction value for those frequencies in a profesional recording studio soundproofing design? Thanks
There are various options to increase the transmission loss at low frequencies depending on the type of construction. INSUL predicts the TL from 50 Hz to 5 kHz. As part of the initial steps of your design you have to come up with your spectral goal inside the studio. Then you need to check on the spectral transmission loss for the different path (e.g., the surrounding walls, doors, windows, floor and ceiling), the available space, construction type (framed construction, masonry,..) and funding for the project. With all that you can start using INSUL going through the different scenarios... the lower the allowable the more detailed you need ensure that have all the sound paths (direct and flanking) covered.

What is the meaning of "deviations" in insul tables description? (Below 100Hz)
