The modern world is increasingly noisy. From vehicle transportation to generators, heavy equipment, wind turbines, and more, the effects of noise on people and the environment are harmful. Scientists have linked human cardiovascular and mental disorders to elevated noise levels. In wildlife, scientists have found that our noisy world affects everything from animal reproduction to disorganizing their predator-prey instincts and communication ability. Noise disruption, in turn, affects our entire ecosystem.

High noise levels have led regulators, planners, and engineers to implement laws, processes, and engineering controls to diminish overexposure to noise. These controls have also led to innovations in noise dampening and insulation products, requiring nonwoven technical textiles to help filter, diffuse, or absorb noise in buildings, vehicles, machinery, and equipment. Additionally, architectural sound insulation has become well-known for private home use and public buildings for their aesthetics and functional sound absorption properties. Some applications involve high temperatures and elevated vibrations, requiring fabrics that withstand heat while protecting people from the sound’s energy impacts.

Fabric performance is directly related to the chosen fiber properties and treatments. Polyester and PET offer excellent tensile strength and abrasion resistance but operate at lower temperatures. Polypropylene has good tensile strength but withstands higher temperatures and has excellent resistance to chemicals like acid and alkalis, which works better in applications with high temperatures and high humidity environments.

Albarrie partners with acoustic panel manufacturers to design and produce nonwoven technical fabrics used to create acoustic products for sound absorption, diffusion, and vibration dampening. Once approved, we create a customizable but repeatable process to ensure your quality standards are met, make it simple to reorder on demand, and create a trusting partnership you can rely on to get your products to market.

The properties that make nonwoven technical fabrics ideal for air filtration are the same for sound. Their porous and web-like structure decreases amplitude as sound waves move through the textile. Noise-absorbing fabrics trap and convert sound waves into heat, softening noise and reducing echo in confined spaces.

Nonwoven technical textiles are lightweight, strong, flexible, moldable, economical, and highly resistant to chemicals and high temperatures for sound and thermal insulation applications.

  • Air Permeability – an essential characteristic of sound-absorbing fabric is airflow resistance or permeability. The material should be open enough to be acoustically transparent but not so open for excessive airflow. An ideal acoustic performance provides a balanced sound pressure level.
  • Porosity – refers to how much air there is between fibers. If a fabric has many air pockets, it will absorb more sound. However, if the material has no holes or is hard, it will block sound instead.
  • Density – is the number of fibers within the material’s area. Needlepunched nonwovens are made from fiber and air. The more fibers within the fabric, the less air space is in between for the same thickness, increasing density. If sound waves aren’t transmitted into or through the fabric, they won’t be absorbed. A material’s density will affect how much sound it absorbs.
  • Tortuosity – the sound becomes muted and distorted as it passes through materials with a higher tortuosity. The more bends in the material’s cell arrangement, the more momentum it loses, which results in a muffled sound.
  • Cells – cell size and arrangement are essential to sound-absorbing performance. The cell size of the fabric must be smaller than the wavelength of the sound it absorbs. The pore size in closed cell materials can impede sound transmission if it’s too large, as some sound can penetrate through them. Open-cell arrangements generally make better absorbers, while closed-cell arrangements make better blockers.

Polyester, Polyester Bicomponent, and Polypropylene fabrics are the most common sound absorbers. However, different fabrics produce different results and accommodate various application needs, whether sound dampening and absorption in heavy equipment or fire-rated material for architectural requirements.

  • Polyester – economic, high strength, and high-density fiber in which sound absorption increases with sound frequency, making it the most effective at high frequencies.
  • Polyester Bicomponent – thermoformable plastic composite fiber from the polyester family is a highly flexible fabric that can be molded and shaped, making it an excellent choice for architectural sound absorption.
  • Polypropylene – acoustic and thermal insulation properties can also help reduce energy consumption.
