What is a Sound Panel?

Sound Panels Absorb Echoes to Reduce NoiseThe term "sound panel" is generic, and can refer to a variety of different types of panels designed to capture echoes.   Sound panels are made of either foam or compressed fiberglass.  Foam panels are filled with tiny pores that accept sound waves, while fiberglass panels are filled with tiny fibers that also capture the sound wave.   With either panel, it is friction that occurs when the sound wave enters the panel system.   The pores, or the fibers, will begin to vibrate against one another as the sound wave enters into the material.  As a result, a mild form of heat is produced, caused by this friction.   Thus the sound wave energy is converted to kinetic energy, and only a portion of the sound wave that "enters" the sound panel will actually survive and reflect its way back "out" of the panel.    With the physics that take place, panel systems are wall or ceiling mounted in a loud room to soften echoes, reduce background noise, lower sound wave reflections, and deliver greater clarity to the original sound produced in the room.   From loud restaurants to recording studios, home theaters to gymnasiums, conference rooms to classrooms, sound panels serve as a key tool in generating more favorable listening environments.   For more information on sound panels, call NetWell Noise Control at 1-800-638-9355 or visit them online at



Why Batting Insulation Doesn't Work

Batting Insulation does NOT block noiseStuffing your walls full of batting insulation may help isolate room temperature, but the treatment does nothing to block noise from bleeding from room to room.   Much like a pile of sponges can't block flooding water, you need sandbags, the same holds true with block noise.   You need density, and fiberglass batting insulation stuffed between wall or ceiling joists is not dense.   In addition, the true path that the noise travels along is structural, much like a string pulled tight between two coffee cans.   The "framing" inside your wall or ceiling most likely is connecting your rooms together.   It is this framing that delivers noise back and forth via vibration.   This means that no matter what you stuff between your joists, behind your drywall, it won't work because the treatment is ignoring the vibration path that the energy is transmitting through.

But lining your surface with dB-Bloc DOES block noiseWhat most contractors of a generation back will think to do, is to stuff the walls full of batting insulation and call the wall "soundproof".   Well in fact, it doesn't work.   What does work is layering mass loaded vinyl, such as dB-Bloc, over the entire surface of the wall or ceiling, then a channel system to disconnect the contact points, and new drywall.   For questions related to your common wall or ceiling noise issues, visit NetWell Noise Control online at or call their help desk at 1-800-638-9355.



How to Quiet A Loud Pool Pump

Build a Frame Around Your Pool Pump

Want to shut down up to 90% of your pool pump noise?

Pool pumps can produce annoying levels of unwelcome noise in an atmosphere designed to deliver calm, comfort and fun.   Loud pool pumps can have an adverse impact on the environment around the pool.   To control the excessive levels of noise, a simple frame can be built around the pump, with a set of QBO outdoor noise control blankets cut to affix to the frame.   As a result, the noise is contained to within the enclosure, protecting the swimming pool and its guests.   For questions on controlling your pool pump noise, call to NetWell Noise Control at 1-800-368-9355 or visit them online at

Then Wrap Your Frame with QBO Sound Barrier Blankets




Cafeteria Noise. How to Lower It.

Cafeteria's fill with noise as crowds gather and voices begin to carry.   Cafeteria's need to have hard, cleanable surfaces, which in turn means those surfaces will also combine to reflect and scatter echoes rather than absorb them.   As a result, echoes carry, background noise builds, and conversation over tables spikes as communication becomes strained.   If you can absorb the echo, however, the background noise will collapse,

Got a Noisy Furnace?

Control Furnace Noise with NetWellIf you have a loud furnace that spills noise into adjoining spaces, wrap the ductwork with a sound barrier lagging product called NetLag and line the inner walls of your furnace room with a sound barrier curtain system called QBS Blankets.   Both of these products are Class A fire rated sound barrier treatments that combat furnace noise.  

Wrap Loud Ducts with NetLagThe blankets will block the noise from bleeding through the furnace room walls and ceiling, while the lagging material wraps around ductwork to prevent noise from vibrating out through the walls of the ductwork.   For more information on furnace room noise, call NetWell Noise Control at 1-800-638-9355 or visit them online at www.controlnoisecom.
