Marshall Day Acoustics INSUL 9.0.22

INSUL是用于预测墙壁,地板,屋顶,天花板和窗户的隔音的程序。地板和屋顶的撞击声和雨声。该程序可以很好地估计1/3倍频程中的传输损耗(TL)或撞击声(Ln)以及加权降噪指数(STC或Rw)或撞击额定值(IIC / LnTw),以用于噪声传递计算或声学设计或规格。

INSUL可用于快速评估新材料和系统,或调查现有设计变更的影响。它使用众所周知的弹性板理论对材料进行建模,包括Ljunggren,Rindell等人发表的关于厚板效应的余量。更复杂的分区是使用Sharp,Cremer等人的工作建模的。

INSUL已有15多年的历史了,在这段时间里已经有了很大的改进。它已经发展了许多版本,并成为了一个利用Windows和Mac环境的非常易于使用的工具,并且通过与实验室测试的持续比较进行了改进,以为各种结构提供可接受的精度。可以输入测试数据以便与预测轻松比较,并且可以保存构造以供以后调用。 INSUL考虑了有限大小的影响,这在预测小样本(例如窗口)以及低频的正常元素时非常重要。像任何预测工具一样,INSUL不能替代测量。但是,与测试数据的比较表明,对于大多数结构,INSUL可以可靠地预测STC值在3dB以内。 INSUL将极大地增强声学顾问和产品制造商快速,自信地指定结构的能力,以实现所需的机载隔音效果。

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.

INSUL can be used to quickly evaluate new materials and systems, or to investigate the effects of changes to existing designs. It models materials using well known elastic plate theory including allowances for thick panel effects as published by Ljunggren, Rindell and others. More complex partitions are modelled using work by Sharp, Cremer and others.

INSUL has been available for over 15 years, and has undergone considerable improvements over this time. It has evolved over many releases and into a very easy to use tool that takes advantage of the Windows and Mac environments, and has been refined by continued comparison with laboratory tests to provide acceptable accuracy for a wide range of constructions. Test data can be entered for easy comparison with predictions and constructions can be saved for later recall. INSUL takes account of finite size effects which are very important when predicting small samples such as windows and also for normal elements at low frequencies. Like any prediction tool INSUL is not a substitute for measurement. However, comparisons with test data indicate that INSUL reliably predicts STC values to within 3dB for most constructions. INSUL will greatly enhance the ability of acoustic consultants and product manufacturers to quickly and confidently specify constructions in order to achieve a desired airborne sound insulation.
