What You Should Know About Soundproofing a Room

Benefits of Soundproofing Your Space 

There are four primary benefits you can enjoy from soundproofing. 

Soundproofing Keeps the Noise Inside 

People install sound cushioning to ensure no one hears what is happening inside their rooms. They also want to avoid disturbing others outside.  

Sound recording studios are a good example. Instruments must be at a particular volume to ensure quality output when recording. However, these levels are considered harsh when heard from outside. Thus, they install sound insulation within the studio. 

Home theaters should also be insulated against noise. Watching a movie in low volume is rarely satisfying. You can enjoy your film without disrupting anybody by ensuring the noise is kept within the theater’s confines. Enhancing the acoustic properties of the makeshift movie house also improves the sound quality that you hear. 

It Makes the Room Conducive for Resting 

Sound absorption does not only keep interior noise from being heard outside. It also prevents external sounds from being heard inside. Your house or room becomes more comfortable for resting, especially at night. You need not worry about being jolted awake by sudden tumult outside your bedroom or residence. 

Insufficient rest can lead to severe health problems. Thus, keeping sounds from entering your bedroom also aids in ensuring your health and wellbeing. 

It Gives Neighbors Peace of Mind 

It’s not only you that benefits from soundproofing. Your neighbors can also enjoy a good night’s rest even though you decide to have a movie marathon at midnight. The insulating material absorbs much of the vibrations so that only a low sound volume makes it out of your property, if ever.  

It Helps You Comply with Anti-Noise Ordinances 

While no state law criminalizes noise within a neighborhood, several ordinances in counties and cities address people who disturb their fellows with noise.  

For instance, Miami-Dade County has a noise ordinance that penalizes property owners that emanates sound that can be heard 100 feet away at night. The regulation defines noise as ruckus from animals, power tools, music, and human shouting.  

How Does an Acoustical Metal Deck Absorb Sound? 

Acoustical composite decks use perforated metal and sound absorbent material to trap the sound. The steel slabs have numerous holes drilled into their bodies. The gaps are padded by an insulating material, usually fiberglass, that rests against the wall upon installation.  

In this setup, the sound waves flow through the holes and hit the soundproofing material. The waves generally bounce back from solid surfaces, but the insulator will absorb them upon impact. Because of this, the deck minimizes sound amplification. 

Perforated metal sheets can lower indoor noise levels by up to 50%.  

Other Materials for Soundproofing 

You can further enhance the acoustic benefits of acoustic composite decking by combining it with other materials, including the following: 


Plywood is an excellent material for absorbing bass and low-frequency sounds. It can keep loud music and footsteps from getting outside the room or through the floor to the rooms below. The wood also breaks up sound waves, reducing echo and lowering the amount of noise reflected back into the space. 

Acoustic Foam 

This material resembles egg cartons with forward-pointing cones and hollow holes. The wedges absorb the sound waves and minimize reflection. They help in preserving the sound when recording by preventing distortion.  

Unlike plywood, however, acoustic foam is ineffective against low-frequency sounds. They are also less durable as well. 

Acoustic Hangers 

Sound can come from any direction. The ceiling is often the most underappreciated source of disturbances. Impact sound from people walking from the second floor could reach the spaces below if no acoustic solution is installed. Acoustic hangers absorb these vibrations to lower or even entirely eliminate noise. 

Mineral Wool 

Also known as wool insulators, this material frequently appears as cavity fillers in residential or commercial properties. They are also employed as additional soundproofing for ceilings and walls. Aside from being resilient against sound waves, mineral wool can also resist fire and moisture. 

Acoustic Caulk 

Like mineral wool, acoustic caulk plugs gaps in corners or between the walls and ceilings. They can also be used between two soundproofing materials, like plasterboards and drywall. However, their soundproofing capabilities are only supplementary in nature and not standalone. You can use them to ensure maximum insulation. 

When Should You Soundproof Your Room? 

There are many scenarios where noise insulation can be very beneficial. You should think about proofing your room against sound if: 

  • Your room sits right next to a source of significant human traffic. 
  • You work home-based, and your job requires an environment with minimal noise. 
  • Your work schedule lets you sleep only when other people are awake and moving about. 
  • You want to set up an amateur home recording studio or home theater.
