Excessive noise in restaurants and bars is one of the most frequent problems affecting the customer experience.
Overlapping conversations, background music competing with voices, the clatter of dishes being carried from the kitchen… When the noise level exceeds 70–75 dB, diners have to raise their voices to communicate, creating a chain reaction known as the cocktail party effect: the more noise there is, the louder everyone speaks, and the more the problem is amplified.
The good news is that there are specific acoustic conditioning solutions for the hospitality industry that allow you to reduce reverberation and control noise without compromising the interior design of the establishment.
Why noise is a growing problem in restaurants and bars
Current trends in hospitality interior design favor open spaces, high ceilings, glass surfaces, exposed concrete, and metal furniture. These materials, while visually appealing, are highly reflective from an acoustic point of view: instead of absorbing sound, they bounce and amplify it.
Added to this is the growing popularity of open or semi-open kitchens, which introduce a constant source of noise into the dining room.
The result is an environment where the reverberation time increases dramatically, making it difficult to hold a conversation at a normal volume.
How Excessive Noise Affects the Customer Experience
The impact of noise in a restaurant goes far beyond mere discomfort. Various studies demonstrate that excessive noise affects the perception of flavor, reduces the time customers spend in the establishment, and decreases the likelihood of repeat business or recommendations.
From a business perspective, a noisy restaurant receives worse reviews, loses loyal customers, and, in many cases, generates complaints from neighbors that can lead to purposes.
Ultimately, noise is a problem that directly impacts the profitability of the establishment.
Main Sources of Noise in a Restaurant
Before proposing solutions, it is essential to identify the source of the problem. The most common sources of noise in a restaurant are:
- Reflective surfaces: high, untreated ceilings, ceramic or microcement floors, smooth glass or concrete walls.
- Open or semi-open kitchens: the noise from extraction, utensils, and communication from the kitchen staff is transmitted to the dining room.
- Air conditioning systems: air ducts and refrigeration equipment that generate constant background noise.
- Capacity and furniture layout: tables too close together without acoustic barriers between areas.
- Poorly calibrated background music: poorly placed speakers or excessive volume that forces diners to raise their voices.
Acoustic Conditioning Solutions for the Hospitality Industry
The goal of acoustic conditioning in a restaurant is not to eliminate all sound, but to control it: reducing reverberation time, improving the clarity of conversations, and creating a pleasant sound environment.
This is achieved by placing absorbent materials at strategic points in the establishment.
Acoustic Ceiling Panels
The ceiling is the most effective surface for acoustically treating a restaurant, as it is the largest unobstructed area. Acoustic panels and baffles are installed suspended from the ceiling and absorb a significant amount of sound energy, noticeably reducing reverberation.
Collections such as Ideacustic are specifically designed for this type of application.
Acoustic wall coverings
The side walls are the second key surface. Installing acoustic wall panels like those in the Ideaperfo collection reduces the initial sound reflections, which are the biggest obstacle for diners to understand each other.
These panels blend seamlessly into the interior design of the establishment and are available in various finishes and colors.
Decorative Panels and Custom Solutions
In restaurants where aesthetics are paramount, solutions combining acoustic function and design can be used: LED backlit panels, customizable fabric panels with the establishment's corporate image, or wood finishes that add warmth to the space.
These solutions go unnoticed as acoustic treatment but have a direct impact on the sound comfort of the premises.
Success Story: Iris Cerámica Group Restaurant at Casa Decor 2026
A recent example of how acoustic conditioning can be integrated into a high-end restaurant project is the restaurant designed by Raúl Martins for Iris Cerámica Group, presented at Casa Decor 2026 in Madrid.
The space, conceived as a high-end gastronomic experience, combined large ceramic surfaces, high ceilings, and a contemporary interior design that, without acoustic treatment, would have generated very high levels of reverberation. Ideatec intervened with double PET panels suspended from the ceiling, a high-performance acoustic solution that integrated seamlessly into the restaurant's design without disrupting the interior designer's aesthetic vision.
The result was a space where diners could converse normally, without raising their voices, and where the background music fulfilled its purpose without competing with conversations.
An example of how well-designed acoustics can become an added value for a business.
