Please consult with us if the following situations may occur, "It becomes troublesome when the next door conversation seeps through to the conference room", "The level of the telephone call and people speaking in the next door office is heard through to the boardroom". The Japanese architecture society has created a need to use a sound insulation performance tabulator, inferring to the adjacent room, in order to use the sound insulation performance tends to be difficult however, saving the tabulated data is possible.
In times such as these, first of all to conduct a sound insulation performance check, you must measure the walls and the doors. Regarding measuring the sound insulation performance, according to the Japanese architecture society, you can estimate the performance by using the sound pressure level difference, from there you can use the sound insulation performance indicator to make a judgment. There is a time when the data for the sound insulation performance is unavailable or insufficient, then with the applicable classification you can give it an index, then to improve the sound insulation performance, you need to confirm the target value, and then making a suggestion regarding the proposed measures is possible.
Moreover, using our omni-directional sound source analysis system 'Noise Vision' makes reviewing the proposed measures a lot easier and speedy.
