7 tips to improve room acoustics

Appropriate acoustics provide a cozy and pleasant atmosphere. So how can we improve room acoustics? Here are a few simple tricks that don’t cost a fortune.

Noisy rooms are unpleasant, so the acoustics can be improved. Sometimes more attention is paid only to the interior, forgetting important details related to sound insulation. In this article, discover 7 tips for improving room acoustics.

Don’t underestimate the sound quality of a room, especially the areas where you spend a lot of time, like the kitchen, bedroom, or living room. Exposure to intense noise can cause auditory trauma, just like noise pollution.

Soundproofing avoids sounds coming from one room to another, or from the street, neighbors or outside machinery . It is a good idea to know alternatives to solving home soundproofing problems.

What is soundproofing?

Noise isolation is to block noise coming from outside and to prevent noise from inside the house from going outside. Use a material with sufficient mass, such as cardboard, plaster, or steel, to create a barrier that absorbs sound waves.

It differs from acoustic conditioning in that the latter is based on improving sound quality inside a room so that it is not reverberant. Thus, conversations, movies or listening to music are more enjoyable .

Both technologies aim to protect space and provide additional comfort.

Recommendations for improving room acoustics

In general, ceilings, walls and floors are flat and contribute to reverberation and reverberation , which can be measured through a method proposed by ‘Mario Guillermo Camín’, the Institute of Acoustics and Acoustics.

If it feels like you’re arriving late because the sound spreads in all directions, can that be improved? In this article, we’ll give you some practical tips to improve your room’s acoustics.

1. Cover glass windows

Larger windows use more glass and therefore generate more vibration, which impairs the acoustics of the room.

If the door or window is made of glass, it should be covered with a soft curtain or thick cloth. Besides decoration, it also contributes to improving the interior acoustics.

Glass emits wave vibrations, such as when playing music, and affects sound clarity . Porcelain and glass have a similar effect because they have poor absorption and eventually become reflectors.

2. Use thick carpet

Continuing the advice on absorbent materials, thick or luxurious fabric carpets are effective, keeping sound in place and minimizing warping on the floor.

3. Moving Furniture

Each element in a room plays a fundamental role in acoustics. Properly placed furniture affects both the reverberation and the time it takes for sound to reach your ears.

The key is  to change the arrangement of items in a room . A preference for upholstered or wooden furniture is also helpful.

4. Room Acoustic Tips: Place Houseplants

Natural plants placed here and there favor sound propagation, break up the waves and direct them in different directions, enhancing resonance.

In addition to sound diffuser panels, ornamental plants have the function of decoration, ambiance, and reducing mental stress.

5. Use Shelves and Bookcases

They provide wood and paper an ideal combination for good acoustics to transmit, transmit and receive waves traveling in a room.

Consider using decorative bookcases that can help balance the energy of other reflective objects, reduce sound wave intensity, and isolate spaces to prevent sound quality deterioration .

6. Try an Acoustic Diffuser

The diffuser moves the sound to its lowest concentration while softening the energy, injecting energy into reflections from other locations. This makes the sound waves progressively weaker, but does not lose power.

An acoustic diffuser that you can easily make at home is the bookshelf just mentioned above!

7. Use absorbent panels

The purpose of installing absorbent panels is clarity of sound. Absorptive panel materials that collect excess energy reflected from walls include foams, membranes, felts, and fabrics.

An easy way to solve this problem is to install unplasticized canvas with the top edge as foam insulation .

Materials that affect the improvement of room acoustics

All building materials have certain basic acoustic properties, but the best or poor sound quality depends on the materials used in the space. The use of concrete in churches is different from building houses.

The same is true for wave absorption in each environment. The better the material absorbs sound, the less reverberant it is. The following list specifies materials related to sound insulation.


  • wood fiber acoustic panels
  • rock wool
  • acoustic foam
  • glass wool


  • glass
  • metal
  • marble
  • exposed concrete
  • stucco brick
  • ceramic tile

In order to know the sound absorption coefficient of a building material, a specific table provided by the Argentine Association of Computational Mechanics can be used as a reference.

In the bedroom, it is good to keep the noise down to relax and avoid health problems.

What you should always have to improve your room acoustics

The main recommendation for adjusting the acoustics of an already built room is to pay attention to the materials for decoration. Soft, porous materials that provide higher water absorption are preferred.

These suggestions include wall or ceiling tapestries, heavy curtains, blankets and carpets. Rugs dampen impact noise, and curtains block sound waves in a wavy shape and act as a diffuser.

The painting in the living room should be without glass. Choose an oil painting instead of a glass-framed image. The glass is reflective and lengthens the booming sound.

Certainly, just redistributing the decorative elements in the living room is enough to improve the room’s acoustics. Apply the tips above and experience a cozy room without missing out when having a group conversation!
