Sound Barriers for Acoustic Insulation

Sound BarriersElasto Proxy explains what engineers need to consider when choosing sound barriers.  This article is the third in a multi-part series about acoustic insulation.

Sound barriers are soundproofing materials that reflect little or no noise. They usually contain dense but flexible mats and one or more layers of acoustical foams such as melamine. Various facing materials are also used for attenuation, protection, and decoration. Sound barriers are designed to achieve maximum attenuation over a broad frequency range, but they can impart other important properties. For example, some sound barriers offer resistance to fire and fluids. Other emit low levels of smoke while burning. (more…)

Sound Absorption and Acoustic Insulation

sound absorptionElasto Proxy explains what engineers need to know about choosing sound absorption materials for acoustic insulation.

Part 1 of this series examined three components of sound (source, path, and receiver) and three types of acoustic insulation (absorbers, barriers, and dampers). Part 2 takes a closer look at sound absorbers, a type of acoustic insulation that’s used both at the source of the sound and at the receiver.

By applying the information in this article, engineers can choose the right sound absorbing materials for applications such as aerospace, defense, infrastructure, mobile equipment, and stainless steel and food equipment. (more…)

Acoustic Insulation Selection (Part 1)

acoustic insulation selectionAcoustic insulation selection starts with understanding the sound source, path, and receiver.  Engineers also need to know the basics about sound absorbers, barriers, damping materials, and facings.

Acoustic insulation absorbs, transmits, or redirects sound waves – vibrations in the air that pass through objects and result in audible sound. Noise, or unwanted sound, is measured in decibels and has a specific frequency distribution. Through material selection and custom fabrication, Elasto Proxy can create acoustic insulation that’s “tuned” to address the frequencies in your application. As this article explains, understanding some basics can help you to get the acoustic insulation that you really need. (more…)

How Exhaust Blankets (Heat Blankets) Support Tier 4 Pollution Control

Exhaust BlanketsElasto Proxy makes exhaust blankets for diesel engines used in off-road mobile equipment. This article is the second in a series about exhaust blankets and the U.S. EPA’s Tier 4 emissions standard.

In Part 1 of this series, Elasto Proxy explained how exhaust blankets are used with diesel-powered equipment to promote compliance with Tier 4, a rigorous emissions standard from the U.S. Environmental Protection Agency (EPA). Engine insulation alone won’t enable you to meet the EPA’s new requirements, but heat blankets support the use of pollution control technologies in the Tier 4 standard.

By keeping these technologies running smoothly, fleet owners and operators can maximize performance and minimize downtime. Heat blankets aren’t your only aftermarket option, but they offer important advantages over heat shields and exhaust wraps. As a custom fabricator of insulation for the mobile equipment industry, Elasto Proxy can make the heat blankets you need to support Tier 4 compliance. (more…)
