Adding a new customer to this list and maintaining a good business supplier-original equipment manufacturer (OEM) relationship can be difficult. Suppliers tend to run into conflict situations that result in customer complaints. Although suppliers can produce products meeting all requirements, once the component or sub-system is integrated, issues may appear. The situation gets even more complicated when an OEM deals with several suppliers and each is convinced their product is flawless. How do you tackle these situations? <\/p>\n\n\n\n
Simcenter\nSoundbrush: Measure and proof <\/strong><\/h3>\n\n\n\nSPINEA can relate to these situations. Their gear boxes were once suspected of causing noise issues. This company would bet their bottom dollar (or Euro, if you will) their components are perfect, meeting the noise level requirements and \u201cinnocent\u201d of causing any noise issues. To ensure and justify the quality of their products, SPINEA\u2019s team began searching for a solution to measure the noise levels and define the root cause of the issue. This is what brought them to the engineering technique called, \u201csound source localization<\/a>.\u201d <\/p>\n\n\n\nSound source localization uses real-time noise measurements to identify the specific noise source. SPINEA decided to invest in Siemens Digital Industries Software\u2019s Simcenter Soundbrush<\/a> solution, which enables the development team to visualize sound intensity in 3D. This tool provides accurate and detailed identification of noise sources, including sound intensity values, sound propagation directions and sound power values during one single and simple measurement.<\/p>\n\n\n\n![\"\"](\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/6\/2019\/10\/Simcenter-Soundbrush-software-1024x505.jpg\")

Simcenter Soundbrush<\/figcaption><\/figure>\n\n\n\nSimcenter Soundbrush<\/a> is very easy to use. There is neither extensive training nor deployment periods needed. \u201cImmediately after the training, we started with the acoustics measurements and analysis of the bearing reduction and the results were great. It was shown that our products are meeting the strict requirements for the maximum allowed noise limits,\u201d says Mr. Olej\u00e1r. \u201cThe noise field is registered by movement of the high-sensitive 3D intensity sensor, which is able to register the direction and intensity sound field around the tested bearing reduction. This is very important to filter out other unwished noise phenomenon from the motor, for example. Thanks to this capability, some of the complaints were revoked.\u201d<\/p>\n\n\n\n\u201cIt\u2019s much nicer to answer the complaint with an explanation that includes visualization.
