Room acoustics have a significant impact on sound quality – even the most expensive sound system cannot function effectively if there are acoustic problems in the room. Common problems such as echo, standing waves or bass buildup in the corners can distort the sound and reduce the listening pleasure.
To improve acoustics, it is important to assess the size, shape, and surfaces of the room and use appropriate solutions. The most popular methods include low-frequency traps, absorption panels, diffusers, and acoustic fabrics. Professional assessment and proper placement of acoustic elements can significantly improve sound quality in both small and large spaces.
Key tips:
- Small rooms : use bass traps in the corners and absorption panels.
- Large rooms : combine diffusers and zone treatment.
- Tests : Clapping, speech comprehension, or music listening tests help assess acoustics.
- Professional solution : acoustic experts can accurately measure problems and offer customized solutions.
Investing in proper acoustics not only improves sound quality, but also ensures a more pleasant atmosphere in the room.
Estimating acoustic problems based on room size
How room size and shape affect sound
The size and shape of a room have a direct impact on acoustic properties, so different sized rooms present different problems.
- Small rooms (up to 20 m²), such as bedrooms, often suffer from bass buildup and standing waves. Low-frequency sounds don't have enough space to disperse their energy, so they accumulate in the corners, causing a rumbling sound.
- Medium-sized rooms (20-40 m²), such as living rooms, often face the problem of reverberation. This is especially true for rooms with high ceilings, where sound "remains" in the air for too long due to the small amount of absorbing surfaces.
- Large rooms (over 40 m²) often have uneven sound distribution. In some areas, certain frequencies may be almost inaudible, while in others they may be too intense.
The shape of the room also plays a big role. Square rooms are the worst for acoustics, as their walls reflect sound equally. Rectangular rooms with a ratio close to 1:1.6 (the golden ratio) are considered the most suitable for Hi-Fi systems. AUTOGARSAS.LT experts advise avoiding rooms with a ratio of 1:2 or 1:3, as they create strong standing waves.
Ceiling height is also important. A standard height of 2.5 m can affect mid-range reproduction, while ceilings that are too low (2.2–2.3 m) create a feeling of pressure and limit the sound dynamics.
Simple ways to check room acoustics
To quickly assess the acoustic condition of a room, several simple tests can be performed:
- Clap test : If the echo persists for more than 1-2 seconds, it indicates that the room has too many reflective surfaces.
- Speech Comprehension Test : If speech becomes difficult to understand, acoustic solutions are needed.
- Music Listening Test : Listen to familiar music in different parts of the room. If you notice that the bass or treble sounds uneven, it's a signal that you need to pay attention to the acoustics.
In addition to these independent methods, AUTOGARSAS.LT offers professional acoustic assessment. Using RTA (Real Time Analyzer) analyzers and calibration microphones, it is possible to accurately measure the frequency characteristics of a room. This helps not only to identify obvious problems, but also to detect subtle sound distortions that can affect the performance of Hi-Fi systems.
Impulse response measurements allow you to determine reverberation time (RT60) and early reflection, which are essential for planning acoustic treatment and proper speaker placement.
AUTOGARSAS.LT specialists also take into account building materials and furniture placement . For example, concrete walls, ceramic floors and glass surfaces, typical of modern Lithuanian homes, require different solutions than wooden structures or carpeting. These aspects ensure that acoustic solutions are tailored to the specific room and its characteristics.
Acoustic solutions for rooms of different sizes
Solving acoustic problems in small rooms
Small rooms often suffer from low frequency accumulation in the corners and standing waves. AUTOGARSAS.LT offers several practical ways to solve this.
Low-frequency traps are a must-have option. They are recommended to be installed in all corners, starting from the floor and up to a height of about 1.2 m. If space is limited, it is important to focus on the corners behind the listening position.
Absorbing panels should be installed at the points of first reflection – on the side walls directly next to the listener and on the wall behind the speakers.
Additionally, hybrid panels , which simultaneously absorb and diffuse sound, are a great solution. They help avoid excessive sound absorption, which can make a space feel too “dead.”
Ceiling treatment is also important in small spaces. Treating about 30-40% of the ceiling area can reduce vertical reflections and improve sound accuracy and stereo imaging.
Next, we will discuss how to apply acoustic solutions in larger spaces to maintain the proper sound balance.
Acoustic solutions for large rooms
Large rooms pose different challenges - it is important to reduce reverberation and ensure uniform sound dispersion.
Diffusers are an essential element that helps disperse sound waves and keep the space “alive.” They are best installed on the back wall behind the listener and on the side walls.
In large rooms, the most effective method is the zonal treatment principle. The listening area is treated with absorbent materials, and the further areas are treated with diffusers. This helps maintain a balance between clarity and a sense of space.
Ceilings in large rooms also require attention. Suspended acoustic panels or special ceiling diffusers reduce early reflections and shorten the reverberation time. For Hi-Fi listening rooms, the recommended reverberation time is 0.3-0.5 seconds.
Don't forget about floor treatment , either. Carpeting or acoustic mats in the listening area help reduce floor reflections that can disrupt the stereo image.
Once all the acoustic elements are installed, it is important to have the system professionally calibrated to meet your specific needs.
Professional installation and individual solutions
AUTOGARSAS.LT offers not only products, but also comprehensive consultations and professional installation , tailored to the needs of each client. The process begins with a detailed acoustic assessment using specialized equipment.
Custom design involves analyzing not only the size of the room, but also its purpose, budget and aesthetics. For example, home theater systems require different solutions than stereo Hi-Fi equipment or professional studios.

Best room dimensions for Hi-Fi sound systems
Ideal room proportions for better sound
To enjoy high-quality sound, it is important to consider the dimensions of the room. Properly balanced room dimensions can reduce the effects of resonances and standing waves, which often distort sound. While the specific proportions depend on the characteristics of the individual space, the general rule is to avoid strictly square rooms. Such spaces cause uneven sound distribution, so asymmetry becomes an advantage.
Ceiling height also matters. Ceilings that are too low can amplify vertical resonances, while ceilings that are too high can cause reverberation, which makes it difficult to perceive sound. If you want to achieve the best result, it is worth contacting professionals. For example, AUTOGARSAS.LT offers specialized consultations and design services that help create the ideal listening space.
