The best way to soundproof a golf simulator is to first find out where the sound is leaving the room. Start with ball impact and the impact screen, then move on to floor vibrations and finally check doors, penetrations and ventilation. Soft surfaces can make the room more comfortable, but they do not replace measures that limit the path of sound into an adjoining room.
This guide takes a different approach from a typical materials list: you test the sound paths in the right order before making changes. This makes it easier to choose a measure that helps your family or neighbours specifically.
What types of sound from a golf simulator do you need to distinguish between?
A home golf simulator produces both airborne sound and sound that can travel through the building structure. Airborne sound includes ball impact against the impact screen, voices and projector fan noise. Structure-borne sound occurs when vibrations are transmitted from the floor, walls or ceiling to adjoining parts of the building.
This is an important distinction because the same measure rarely solves both issues. The Swedish National Board of Housing, Building and Planning’s regulations on protection against noise in buildings, BFS 2024:10, cover, among other things, sound level differences between spaces, impact sound and sound from installations. Read Boverket’s guidance on noise protection in homes for the building-technical framework. For a golf simulator, this means that an echo in the room and a thud at a neighbour’s home should be treated as two separate issues.
How do you test which sound path is causing the most disturbance?
Carry out a simple listening test before buying materials. Ask someone to listen in the room next to, above or below the simulator room while you play each sound source separately. Test with the door closed and note what can be heard most clearly.
-
Hit five balls with a normal swing and listen to the ball impact against the screen.
-
Stand on the hitting mat without hitting and shift your weight between your feet to hear whether the floor transmits vibrations.
-
Turn on the projector, computer and any ventilation without hitting a ball.
-
Repeat the test with the door ajar and with the door fully closed.
Write down whether the disturbance sounds like a sharp impact, a dull thud or a steady hum. This becomes your priority list. If the dull thud is most noticeable in a room on the other side of the floor, it is often more relevant to review the floor construction than to add more absorbers to the wall.
What should you do if ball impact against the screen is the clearest sound?
Start with the hitting area and check that the simulator is correctly installed. An impact screen should catch the ball in accordance with the manufacturer’s instructions, and the frame should stand securely on a level, load-bearing floor. The installation instructions for SimBooth 3 state that the impact screen is important to the stability of the structure and that the structure must not be modified or loaded in the ceiling area.
Therefore, avoid hanging heavy boards, mats or other additional weights directly on the frame or impact screen without first checking what is permitted for the specific model. When planning a complete solution, Simgolf Scandinavia can help you start with the room, the simulator components and a safe installation. It is a more reliable approach than trying to compensate for an incorrect installation afterwards.
How do you limit vibrations from the hitting mat and floor?
Treat vibrations at the source before enclosing them. First check that the hitting mat, floor panels and any furniture are level and are not knocking against walls or one another. A structure that is in contact with several hard building elements can transmit vibrations even when the room itself feels quieter.
A decoupled construction means that a vibration-producing component is separated from the load-bearing building element with a suitable resilient solution. The construction that works depends on the floor structure, the floor’s load-bearing capacity and how the room is used. Boverket’s handbook Noise protection in homes and premises describes how measures close to the sound source are often most effective and how impact sound concerns sound from impacts or shocks against the building structure.
If the simulator room is above a bedroom or in a multi-unit residential building, it is wise to have a building professional or acoustician assess the floor construction before choosing a permanent solution. Do not make any changes that affect fire protection, load-bearing capacity or ventilation without the proper basis.
Do acoustic panels and textiles help with disturbances outside the room?
Acoustic panels and textiles primarily reduce reverberation in the simulator room, not necessarily sound transmission to the next room. They can make ball impact feel less harsh for the player and improve speech clarity, but sound that travels through a gap or into the building structure requires a measure along that path.
Therefore, place absorptive materials where they improve your own sound environment, for example on clear wall surfaces that do not affect the swing area or safety. Then evaluate using the same listening test. If the sound outside the room is unchanged, do not interpret this as meaning the material is wrong; it is more likely that the issue is sound insulation or structure-borne sound rather than reverberation.
Why are doors, gaps and equipment important in a sound plan?
Small openings can become the clearest sound path when walls and floors are already solid. Check how the door connects to the frame, cable penetrations and where air passes between rooms. Airtightness must always be combined with working ventilation, so never block supply air, extract air or other functions the room needs.
Also listen to the sound produced by the equipment itself. A projector, computer or fan that is acceptable during play may be disturbing when the house is quiet. Position equipment securely, avoid letting it rest against resonant panels, and compare the sound before and after each change. This makes it clear whether you have reduced the actual disturbance or merely changed the acoustics of the room.
When should you seek professional help?
Get help when the measure affects load-bearing elements, fire separation, ventilation or a floor structure between dwellings. Boverket describes noise protection as a technical performance requirement and notes that the requirements may be relevant when buildings are altered. A qualified assessment is especially valuable when the simulator will be located close to bedrooms, in a condominium apartment or in premises with multiple users.
For most home rooms, however, the best first investment is a clear test plan: identify the sound source, try one measure at a time and listen from the room where the disturbance actually occurs. This provides a more accurate basis for both room planning and choosing a golf simulator.
Frequently asked questions about soundproofing a golf simulator
Are acoustic panels enough in a simulator room?
No, not if the main problem is sound that can be heard through the floor, wall or door. Acoustic panels can reduce reverberation in the room, but start with a listening test to determine whether the disturbance is airborne sound, vibrations or a leaky connection.
Which sound should I address first?
Address the sound that a listener in the affected room perceives most clearly. For many people, this is ball impact against the screen or a dull impact in the floor, but the projector, fan and door gaps can also be decisive.
Can I enclose the golf simulator completely against walls and ceilings?
Avoid modifying or loading the simulator frame, impact screen or ceiling area without following the model’s installation instructions. Also check the swing area, ventilation, fire protection and access for servicing before building permanent enclosures.
Do I need to consider regulations when soundproofing at home?
Yes, especially if the work changes building elements or affects fire protection and ventilation. Boverket’s guidance on noise protection explains that the requirements apply to new construction and may be relevant when buildings are altered. Consult a qualified professional if you are unsure.
How do I know whether the floor is transmitting vibrations?
Ask someone to listen in adjoining rooms while you shift your weight on the hitting mat and then hit a few balls. A dull thud that is heard more clearly outside the simulator room than inside it is a sign that transmission through the floor and building structure needs to be investigated.
