If you’re looking to reduce sound levels in your jet engine testing facility, noise canceling curtains, also called soundproof curtains or sound dampening panels, may be your answer. Here, we’ll discuss why you might need noise curtains, how they work, and how you can use them to reduce noise.
Jet Engine Testing Noise
Jet engines produce sound levels ranging from 140 to 160+ decibels, depending on their thrust and a person’s proximity to them. For comparison, 140 dB is the threshold of pain for human hearing, and many facilities test engines for extended periods, making continuous exposure a serious health risk. In fact, according to studies, 16 percent of workers with jobs in noisy workplaces like jet engine testing centers experience some degree of hearing loss.
These high levels of noise come with other challenges as well. You may be struggling with sound that’s bleeding into nearby workspaces, and you might worry about meeting OSHA safety standards.
If you’re looking for a solution that avoids undergoing construction, noise curtains can help by creating a barrier between the noise and everyone else.
How Noise Curtains Work
Noise curtains are large, durable panels designed to absorb and block sound. Typically, they’re made with heavy-duty materials that trap and dampen sound waves. Unlike rigid walls, these curtains can be moved around as needed, making them great for industrial spaces where flexibility is important. Additionally, heavy-duty curtains like the ones we offer at Singer Safety are designed specifically for environments like jet engine testing and maintenance facilities, where ordinary curtains wouldn’t stand up to the constant vibration and noise.
When used properly, soundproof curtains can help reduce overall decibel levels, limit echoes, stop noise from spreading throughout the rest of your facility, create safer zones for technicians to focus, and keep nearby teams productive.
How Do Noise Curtains Improve Engine Testing Noise Control?
Noise curtains are specifically useful in jet engine facilities.
Flexibility for Different Test Setups
Jet engine tests can vary from small auxiliary power units (APUs) to large engines. Fixed acoustic walls won’t be able to move as your work changes, but curtains can.
With a track system or modular panels, noise curtains allow you to create temporary enclosures, adjust layouts for different engine sizes, reposition quickly, and later reconfigure the same space for other tasks.
Reduce Decibel Levels
Sound dampening panels can give you noise reduction ratings (NRRs) anywhere from 10 to 20+ decibels, depending on their configuration. In a large facility, even a 10 dB reduction can cut perceived loudness by half. By using layered materials and strategic placement, you can drastically reduce the noise of your tests.
Complement Existing Test Cells
Most aerospace facilities already have some form of hard-shell acoustic treatment. This is a good start, but it doesn’t help if you need to add new equipment or change your testing stations. Noise curtains can bridge the gap by filling in acoustic “leaks,” dividing larger hangars into smaller zones, and improving performance without needing to renovate.
Improve Safety
Beyond the obvious discomfort, studies show that excessive noise can increase stress levels, reduce concentration, and contribute to both hearing fatigue and hearing loss over time. Additionally, constant loud noises can make it harder for people to hear each other, which makes job sites less safe due to the potential for miscommunication and accidents. It’s for these reasons that using noise curtains is so important.
Curtains vs. Panels
If you’re wondering whether to use sound dampening panels or noise curtains, the truth is that you can usually benefit from both. However, their strengths do differ, and we cover those differences here.
Sound Dampening Panels
These are designed to be installed permanently and are best for reducing echo when mounted on walls or ceilings. They can also serve as a foundation layer in your overall strategy.
Noise Canceling Curtains and Soundproof Curtains
These are best for creating acoustic partitions wherever you need them. They’re especially useful in engine testing areas or other places where setups change frequently, and you need to adapt quickly.
FAQ About Noise Curtains for Jet Engine Testing and Maintenance Facilities
Can soundproof curtains really reduce jet engine noise?
Yes. While they won’t eliminate noise completely, high-quality soundproof curtains can significantly reduce decibel levels.
Do noise curtains meet aerospace safety standards?
High-quality noise curtains designed for industrial use typically meet fire resistance and safety requirements needed for aerospace facilities. Always check for fire ratings, heat tolerance, and material certifications when selecting a product.
Are noise curtains good for engine testing noise control, or do I still need a test cell?
Noise curtains complement existing test cells but don’t replace them. If you already have a test cell, curtains help seal noise leaks, reduce echo, and create quieter areas for technicians to work.
Will noise curtains interfere with maintenance work?
Not at all. Noise curtains are designed to move with your team.
How durable are noise curtains in a jet engine facility?
Very durable. Industrial noise curtains are made to withstand heat, vibration, and the general wear-and-tear of aerospace work. Many also have replaceable outer skins for longer use.
Can I use noise curtains for temporary testing setups?
Absolutely. This is one of their biggest advantages. Noise curtains work extremely well for mobile test stands, short-term diagnostics, and any situation where you don’t have a dedicated sound-controlled room.
Do noise curtains help with OSHA compliance?
Yes. By reducing overall noise exposure and creating quieter technician zones, noise curtains help you stay compliant with OSHA hearing protection standards.
