Sound Insulation Simulation Program INSUL Acoustics Software

The Ultimate Standard in Acoustic Services

From Trandar Acoustics' experience in providing both Research and Development and

as an expert acoustic consultant, we found that installation or construction based on selecting

materials that are good enough still doesn't truly meet the customer's desired objectives.

Therefore, Trandar Acoustics introduced software services, namely the INSUL program, to allow customers to

understand the actual original sound levels and the sound levels that can be made acoustic. It also helps

prevent errors in material selection.

INSUL is a sound insulation simulation program (INSUL Acoustics Software) which is convenient,

fast, and accurate in calculating various values. It is mostly used to predict the sound insulation performance of

wall systems, and can effectively predict the properties of various materials. It is a program

that calculates the sound insulation values of walls, floors, ceilings, and windows. It displays the transmission loss in the form of

1/3 OCTAVE BANDS frequencies and the Weighted Sound Reduction Index (STC or Rw), and can

calculate sound insulation values. It can adjust materials or change designs. It is convenient, fast,

and accurate in calculating various values.

Currently, INSUL is a popular software used by all factories producing gypsum boards, fabric

ceilings, and walls. Let's see how the INSUL program can benefit you!!

5 Benefits of the INSUL Program for Excellent Acoustic Applications

1. Predict Transmission Loss of Impact Sound and Rain Noise

INSUL is a program for predicting the sound insulation of walls, floors, roofs, ceilings, windows, impact sound and

rain noise of floors and roofs. The program can provide good estimations of Transmission Loss (TL) or

Impact Sound (Ln) in 1/3 octave bands and the Weighted Sound Reduction Index (STC or RW)

or Impact Rating (IIC / LnTw) for calculating noise transfer or design or acoustic requirements.

2. Evaluate Material or Design Changes

INSUL can be used to quickly evaluate new materials and systems or check the effects of

changes to existing designs as material models. It uses well-known elastic plate theory, including allowances for

thick panel effects as published by Ljunggren, Rindell, and others. More complex partitions

are modeled using the work of Sharp, Cremer, and others.

3. Continuous Development

INSUL has been available for over 15 years and has undergone significant improvements during this time. It has been developed in

many versions and has become a very user-friendly tool that leverages the Windows and Mac environments.

It has been continuously refined by comparison with laboratory tests to achieve acceptable

accuracy for a wide range of constructions.

Test data can be easily entered for comparison with predictions, and structures can be saved tobe recalled later.

4. Identify Constructions with Speed and Confidence

INSUL considers effects of size and area limitations, which are very important when predicting areas

in small sections such as windows, and for common normal components with low frequencies as well.

However, INSUL cannot replace measurements. Nevertheless, regarding comparison with

test data, it indicates that INSUL can reliably predict STC values within 3dB in most construction projects.

This will enhance the ability of acoustic consultants and product manufacturers to identify structures

quickly and confidently to achieve the desired airborne sound insulation.

5. Multilingual Functionality

INSUL can be switched to display information in English, French, German, Polish, Spanish, Swedish, or

Mandarin. The translation is carried out by acoustic experts to best suit the technical terminology commonly used

in each country.

Noise problems are a significant issue that commonly occur in office buildings,

residential areas, or even in industrial factories. It is a risk that negatively affects

work significantly. Especially in industrial factories, which are the noisiest workplaces, due to

the operation of machinery, it can cause disturbance and prevent employees from working effectively.

If you want to create a good and efficient working environment, Trandar Acoustics therefore enhances its

services with INSUL Acoustics Software, providing peace of mind and worry-free solutions. No need to rework orrebuild structures in the future.
