Sound Meter For Professionals




Sound meters are instruments used to measure sound. These instruments are used for various applications. A sound meter can be used for troubleshooting machines and other mechanical equipment. Abnormal noise is a common sign of mechanical problem. Sound meter makes it easier to pinpoint the source of the problem and the cause of the noise. The sound meter is also to test if soundproofing measures are sufficient to regulate noises inside a building. Another use is the tuning of engine, wherein performance must be balanced with exhaust sound to make sure the vehicle passes noise regulations.


Professionals looking to procure a sound meter must be careful in selecting a product. A sound meter must provide accurate and precise measurements. Professional reputation and growth are largely dependent on the quality of work. And quality results greatly depend on accuracy and precision of the instruments.


Carrying a sound meter all day is no easy task. That is why a sound meter for a professional must be easy to carry. It helps keep fatigue down and helps with avoiding dropping the instrument and damaging or losing it.


Given how sound management is used for various applications, it is important to have a sound meter that can be used for various functions. Sound meter must be reliable and durable so that it can work when needed and even in adverse conditions.


Practical data management is important for professionals. Easy access, organization, and reporting of said data helps speed up completion of the project.


Lastly, the sound meter must be reasonably priced. As good as a sound meter maybe, there is no use for it if one cannot afford it. Professional-grade sound meters don't necessarily have to be expensive. In Sweden, Nordtec is a company that offers a wide range of sound meters with different specifications and prices to suit the needs of any professional.

Passing The Transport Agency Inspection With Aftermarket Exhaust








Aftermarket exhaust, improve performance, aesthetics and give vehicles, from cars to motorbikes, sportier sounds.


Some aftermarket exhaust removes the part of the stock exhaust with the catalytic converter. The catalytic converter helps reduce the number of carbon emissions. It makes vehicle comply with emission standards. Its absence is sure to make the vehicle fail the emission test.


The installation of aftermarket exhaust usually comes with remapping of the engine control unit or ECU. The ECU controls the fueling of the vehicle among other things. A stock ECU is designed for fuel economy. It can be tuned for performance and match it up with the aftermarket performance. The tradeoff is that the vehicle becomes less fuel efficient and produces more carbon.


Then there is the issue of sound. Vehicle noise is regulated to protect the wellbeing of people. The vehicle has to undergo a test using a sound meter during the inspection. You can already see the problem here.  The added performance from the aftermarket exhaust normally comes with additional noise. The added noise can cause the vehicle to fail the sound test.


If the aftermarket exhaust eliminated the catalytic converter, it would be very hard to pass the emissions test.  The best course of action is to reinstall the stock exhaust system or the link that contains the converter. Then you need to restore the ECU mapping to stock. With the sounds test, some exhaust can be installed with a baffle to lower the decibels.  If that is not possible, you will have to reinstall the original can. The amount of work and time to do all these are actually not that much.

Restoring the ECU map is fast and easy. You just need the harnesses and software on your computer. Anyone who is into performance driving has all these. Reinstalling the catalytic converter and adding a baffle won't take more than an hour for anyone who has done it before.


Aftermarket exhaust is great for many reasons. But passing the transport agency inspection is going to require a bit of work. Still, that is a sacrifice many are more than willing to take to make driving a fun and stimulating experience.

Noise Control



Exposure to loud noises can have harmful effects on health. Some example of adverse health effects are constant headaches and nausea. The prolonged exposure to a noisy environment can cause permanent hearing damage. These are just some of the direct effects of loud noises. A noisy environment is very stressful and stress has been linked to various health problems. This is the reason why there are regulations in place that limits the amount of noise generated by any operation.




Much like everything in the world, there are downsides to noise regulations. To certain businesses, these can make it difficult to acquire the needed permits and licenses to operate. A sound meter is used to determine the noise levels. If noise levels are over the limit, noise control measures must be implemented.

There are two ways to control noise. One method revolves around the source of noise. Replacing the old combustion engine with an electric motor is a good example of controlling the source of noise. This method can be expensive. There are cases in which nothing can be done with the source of noise. Such is the case with a fitness gym, in which noise from gym-goers grunting and dropping weights is impossible to stop.

The other method focuses on noise transmission. Going back to the fitness gym as an example, noise can be controlled by lining the walls with noise insulation materials. This  way, all the noises generated are contained within the gym and are not transmitted outside to other offices or buildings.
