The Importance of Noise in machines

Noise is a major issue in automotive and industrial applications. It can be used as an indication that something is happening in the system or machine. Noise depends on the source where it is coming from and also the type of noise the machine or vehicle makes. Let's look at the source aspect first. The sources of noise can be classified into two categories - external and internal:

1. External noise is created by the environment, such as traffic, construction, or birds chirping.

2. Internal noise comes from within the car or machinery itself, including bearings running at high speeds or gears turning rapidly

Similarly, there are two types of noises in a machine - structural and operational.

1. Structural noise, or "noise from the machine," is caused by physical characteristics such as size, weight, shape, vibration frequency, etc.

2. Operational noise, or "noise due to operation," can be reduced with soundproofing materials that absorb vibrations and reduce loud noises when operating machinery

The noise is an important indicator to gauge the health of your vehicle or industrial application. As we all have experienced that Noise is an indicator for other problems in your vehicle, such as worn-out brakes or dirty fuel injectors, or just engine issues. Some noises are harmless, while others can be indicators of serious problems. A mechanic will diagnose the source and severity of any noise coming from your car. If you're experiencing a high-pitched squealing sound, it could mean bad brakes or worn tires; if there's no other noise, check for loose gas hoses or belts. If your engine makes knocking sounds when starting up, this might indicate low oil pressure or dirty air filters – get these checked out immediately! One way to diagnose an issue in a machine or vehicle is to just understand the source of the noise and how you can diagnose the problem. That is exactly what we at Novolytics are looking to build, a mobile app that can empower technicians in faster defect inspection and diagnosis just by listening to the noise using our AI + ML-powered sound analytics technology (we call it Novolytics Hark Engine - A noise diagnostics automation software). So the next time you are getting a regular maintenance check done by a professional mechanic, you would notice that your technician would actually be noticing any out-of-ordinary sound first to determine the issue. Once the source of the noise is detected, it's just a matter of how to fix any issue you may have with your car!
