Have you thought about it? Tiles influence the sound in any room?
When we think of tiles, we usually associate them with aesthetics and functionality in spaces such as kitchens, living rooms, offices, bathrooms or outdoors. But did you know that tiles can also influence the acoustics of a room? Although it is not often talked about, choosing the right tiles can improve or worsen the sound quality within an enclosed space, directly affecting comfort and the sound experience at home. Here are some details.
How do tiles affect acoustics?
Tiles are hard, non-porous materials, which means that,unlike soft surfaces such as carpets, curtains or upholstered furniture, tiles do not absorb sound. Instead, they reflect it. This behavior has different effects, depending on the type of room and the intended use of the space.
About sound reflection
When sound is emitted in a tiled room, the sound waves bounce off hard surfaces. This can cause what is known as “acoustic reflection,” a phenomenon where sound bounces back toward the listening area, creating possible echoes or a feeling of “reverberation” in the environment. In a small or closed tiled room, this effect can be quite noticeable and annoying, as sounds are multiplied and not dispersed as they would be in a space with absorbent materials.
Tile has minimal sound absorption
Unlike other building materials, such as wood or acoustic panels, tile does not have the ability to absorb sound waves. This means that if you have a room with a lot of tiled surfaces (such as a bathroom with tile on the walls and floor), sounds generated within the space — such as voices, appliance noises, or shower water — can bounce around and make the room sound louder or more “empty.”
How does this affect different spaces?
- Kitchens and bathrooms: Tile is an ideal choice for kitchens and bathrooms because of its water resistance, ease of cleaning, and durability. However, these rooms are often relatively small, and because they are tiled, the lack of sound absorption can lead to noticeable reverberation. In kitchens and bathrooms, this effect can make sounds from everyday activity (such as the sound of chairs scraping, running water, or voices) more resonant and less pleasant to the ear.
- Living and dining rooms: In larger rooms, such as living rooms or dining rooms, sound reflection from tiles can create an unbalanced sound environment, with echoes or reverberations that disrupt the clarity of the sound. If activities such as listening to music, watching television, or having conversations take place in a tiled room, the sound can become less defined, making the listening experience less pleasant.
- Work or study spaces: In spaces such as offices, studios, or libraries, tiles can be counterproductive if the goal is to have a quiet environment. Excessive sound reflection can make the environment feel noisier and make it difficult to concentrate, as echoes can disrupt voice clarity on video calls or phone conversations.
Solutions to improve acoustics with tiles
Although tiles, in general, are not the most suitable material for sound absorption, there are ways to mitigate their effects and improve the acoustics of a space without sacrificing aesthetics or functionality.
- Using textured tiles: Tiles with textured or embossed finishes can help disperse sound waves and reduce reverberation. These small irregularities in the surface allow sound waves to deflect and not bounce back directly.
- Combining with other absorbent materials: If you want to keep tiles on your walls or floor, one option is to combine them with more acoustically friendly materials. For example, incorporating carpeting, acoustic ceiling panels, or upholstered furniture into spaces can help balance the overall acoustics of the room.
- Using tiles with special properties: There are tiles specifically designed to improve acoustics. Some manufacturers offer products with special coatings that increase sound-absorbing capabilities. These tiles can be an excellent choice for those looking to reduce noise in environments such as offices or recording studios.
- Room layout: In addition to the choice of materials, the overall layout of the room influences how sound waves are distributed. Including bookshelves filled with books, heavy curtains, or furniture with thick upholstery can also help soften the acoustics in a tiled space.
How Tile Size and Type Affects Room Acoustics
The impact of tiles on acoustics depends not only on their material, but also on their size, shape, and type. Changing these elements can significantly alter how sound waves behave in a space, as each characteristic influences sound reflection, absorption, and dispersion differently. Let’s look at how Large Format Tiles affect this:
- Sound Reflection: Due to their size, large tiles tend to reflect more sound than small ones. The absence of many joints creates smoother surfaces, making it easier for sound waves to bounce around and linger. In rooms with lots of large tiles, such as a kitchen or bathroom with large-format walls, sound can be more resonant and create reverberation.
- More acoustic “void”: Without as many interruptions (such as the grout lines that small tiles provide), sound doesn’t disperse as much and the room can feel “empty” in terms of sound, which could be uncomfortable if the space is poorly laid out.
In contrast, smaller tiles (traditional formats, such as 10×10 cm or 20×20 cm) tend to be more effective at dispersing sound and reducing acoustic reflection.
- Sound dispersion: The joints between small tiles create more uneven surfaces, which helps to spread out sound waves and prevent them from being reflected directly. This can reduce echo and reverberation in the space.
- Better acoustic control: In spaces where acoustics are a concern (such as offices or study rooms), small tiles offer more effective acoustic control, as the more irregular surfaces disrupt sound waves and distribute them more evenly.
Conclusions
For large spaces or those with large-format tiles, try combining tiles with other absorbent materials such as rugs, curtains or upholstered furniture to balance reflection and avoid empty acoustics. Remember that each type of tile has its own acoustic characteristics, so it’s important to choose the right material based on the use of the space and the ambiance you want to create.
