Speaking of power regulation, transformers are everything. Step-down and step-up transformers can enhance or reduce voltages to apply whatever level of power is required for a given application, and as long as transformer noise is not part of the electrical system, they will do their job efficiently and dependably. But transformer sound can be a substantial issue. Even small amounts can back up the works and power transformers from working the way they are designed, should so it is vital to know precisely what transformer noise is, what exactly is causing it, and how to prevent it. What follows is a testimonial of those three aspects of transformer performance, along with some proper suggestions and a review of two of the best transformer products in the industry.  What causes the humming noise in an electrical transformer and how is sound measured? One of the most common symptoms of extra transformer noise is that familiar humming noise that transformers give out. However, determ...

Why are music venues better for concerts than others? Though our eyes might be captivated by the lovely ornate interior of a historic auditorium or the contemporary architecture of a concert hall, our ears are the best and truest judges. For years, the O’Neill Engineered Systems has worked to enhance music spaces for rehearsal and performance. Two vital acoustical concepts, echo and reflection of sound and echo play vital roles in determining what our ears hear and how good a venue sounds. This week’s post will discover every concept and a related product designed to positively impact it.  Reflection of sound- Emphasizing sound with shells Just like bouncing off a mirror, sound waves reflect off hard surfaces within a performance space including the ceiling, floor and walls.  Echo- Curbing sound with Banners Another vital acoustical concept for performance spaces is echo, which is the persistence of sound in a confined space. Sound waves radiate through the air until they str...

For many project managers and business owners, one of the biggest worries about investing in a generator has been noise control. Noise Pollution is a true issue in different parts of the world and just like air pollution; it can have negative impacts on the people it reaches. But just like carbon emissions have been strikingly lessened in the past few decades due to engineering developments and rigorous regulations, contemporary sound attenuation technology is now able to lessen much of the engine noise emitted when a generator set is running thanks to the use of an exhaust generator silencer . Depending on the ambience of your amenity, the local ordinances and the application you might need a high-end level of silencing, or minimal sound dampening might suffice with a construction barrier .  If a new generator set is of an open configuration, it generally won’t come with a silencer, but many manufacturers provide them as accessories. Use the following information to learn about th...

While you might think different styles have benefits over others, it is basically the density of the panels that make a difference.  What sound insulation foam does? Sound insulation foam is an effective way to eradicate reverberations and absorb sounds in your room. The panels are made from robust, open-cell polyurethane that can substantially lessen the amount of reverberations, noise and echoes. Sound insulation foam is one of these types as it is both porous and soft. When a sound wave comes in contact with acoustic foam, it transforms some of that energy into heat which causes decay much faster than if there was no material present at all! Various densities of acoustic foam Acoustic foam comes in different densities and shapes. The biggest difference in performance is density, not the actual design or shape of the acoustic foam.  Each density absorbs sound waves at various frequencies. Thinner acoustic foams will absorb the high and mid spectrum sound waves while denser ...
