Where does the noise in padel come from?

Padel is a great sport, but anyone who wants to build a court next to homes or in a busy location sooner or later runs into the same subject: noise. Noise nuisance from a padel court is one of the questions we are asked most often, and rightly so.

The noise of a padel court is different from tennis: it carries further than you would expect and municipalities are setting ever higher requirements. In this article we explain where the noise comes from, how far it reaches and what you can do about it.

Where exactly does the noise in padel come from?

The noise in padel comes from two sources: the contact between racket and ball, and the contact between the ball and the walls of the cage structure. That second source, the ball hitting glass or mesh, is by far the biggest cause of the perceived noise nuisance. The cage structure also amplifies the sound like a kind of sounding board.

Racket and ball

With every shot, racket and ball produce a short, sharp crack. This sound is comparable to tennis, although it sounds slightly different because of the shorter racket and the perforated balls. On its own this sound is not too bad, but during a game of padel dozens of shots are hit per minute. That adds up.

Ball against glass and mesh

This is the real culprit. In padel, playing off the walls is a fixed part of the game. The ball hits the glass back walls and steel mesh sides with force. Glass vibrates and reflects sound strongly. The mesh, mounted on a steel frame, amplifies and spreads the sound further.

Together, these surfaces produce an average sound power level of around 91 dB. By comparison, with tennis it is roughly 10 dB lower. That sounds like a small difference, but in practice 10 dB means the sound is perceived as twice as loud.

The cage structure itself also plays a role. Because the structure forms a closed whole, sound is reflected and amplified internally before it escapes. This makes padel considerably louder as a sport than most people expect beforehand.

How far does the noise from a padel court carry?

The noise from a padel court is still clearly audible at distances of 40 to 100 metres, depending on the surroundings, the wind direction and the presence of noise measures. Without any damping, the sound can carry even further in open terrain or in quiet surroundings.

How far sound carries depends on several factors. An open site without buildings or vegetation lets sound travel much further than a location surrounded by buildings or trees. Wind direction also plays a part: when the wind blows from the court towards homes, local residents experience more nuisance. Hard surfaces such as asphalt, concrete and facades reflect sound and amplify the effect.

In urban environments, where buildings partly absorb and block sound, the nuisance is smaller at greater distances. But in residential areas with low-rise buildings and little vegetation, or at open sports parks on the edge of a neighbourhood, the noise from a busy padel court can still be heard hundreds of metres away. That is exactly the situation in which municipalities ask for an acoustic study.

Why do local residents complain about padel so often?

Local residents complain about padel because the noise is not only loud, but also has a specific character that is experienced as disturbing. The repeated, hard impacts of the ball against glass and mesh are impulse sounds: short, sharp peaks that irritate the ear more than a constant background noise of a comparable level.

On top of that, padel is generally played at fixed times, namely in the evening and at weekends, exactly when local residents are sitting outside or have their windows open. The combination of the time and the character of the noise makes the irritation greater than the measured decibels alone would suggest.

Another factor is the growth of the sport. Padel has become hugely popular in recent years, and many venues have expanded quickly without the noise having been properly mapped beforehand. Local residents who first had one court now see four or six. That changes the situation drastically. Municipalities respond with stricter requirements, and the threshold for local residents to object has become lower as the nuisance has appeared more often in the news.

What are sound-absorbing panels for a padel court?

Sound-absorbing panels are special panels that are attached to the outside of the mesh of the cage structure. They absorb the sound that would otherwise be reflected out through the mesh. The result is a clearly audible noise reduction, without changing the playing experience.

The panels have been independently tested in an acoustic laboratory. The test results give a good picture of what you can expect in practice:

• Sound absorption class: A (the highest class)
• Absorption coefficient αw: 0.80
• Absorption index DLα: 8 dB
• Airborne sound insulation Rw: 22 dB
• Sound insulation index DLR: 19 dB

In practice this means a clearly audible reduction in noise nuisance at distances of 40 to 100 metres. The panels can be placed on one side, for example the side facing homes, but also around the whole court or only on the lower metres of the cage. They can also be fitted afterwards to existing courts.

There is one important technical point to bear in mind: as soon as panels are attached to the cage structure, wind permeability decreases. The structure therefore catches more wind, which puts extra load on the steel structure. This means the cage structure must be structurally reinforced before panels are installed. That calls for a new calculation per location. Do not skip this step, because it has direct consequences for the safety and lifespan of the court.

What solutions exist for noise nuisance from padel?

There are two main solutions for noise nuisance from a padel court: sound-absorbing panels in or on the cage structure, and a freestanding noise barrier next to the court. In many cases a combination of both is the most effective.

Sound-absorbing panels

Panels dampen the noise at the source. They are attached to the outside of the mesh and absorb the sound before it spreads. This is the most accessible solution, both in terms of cost and execution. The court stays visually open and the dynamics of play do not change. As described above, however, the cage structure must be structurally calculated and, if necessary, reinforced when panels are installed.

Noise barriers

A noise barrier is a freestanding structure placed next to or around the padel court. Barriers work differently from panels: they block and absorb the sound further away from the court. They can be built up to 6 to 8 metres high and be tens of metres long. Noise barriers are particularly useful when the nuisance is directed at one specific direction, for example a residential area directly next to the sports park.

A noise barrier is a structure and almost always requires an environmental permit. Structural calculations and cone penetration test data for the subsoil are also needed. Barriers can be finished with coconut-fibre or green screening on which climbing plants grow. This gives a natural look and is generally better accepted by municipalities and local residents.

Combination of panels and barrier

In many situations a combination works best. The panels dampen the noise at the source, so the noise barrier can be lower. That saves costs and makes obtaining the permit easier. Which combination fits best always depends on the location, the distance to homes and the requirements of the municipality.

Finally: the choice of the right foundation can also help reduce noise. Thanks to its porous structure, drainage concrete has a slight sound-absorbing effect. Supersub, a foundation solution based on foam concrete, also has sound-damping properties. These are not substitutes for panels or barriers, but they can make a positive contribution to the overall picture.

Can you simply build a padel court next to homes?

No, you cannot simply build a padel court next to homes. In the Netherlands a padel court is regarded as a structure and falls under the building regulations. In most cases an environmental permit is mandatory, and for a location near homes an acoustic study is almost always required.

The permit requirement certainly applies to outdoor courts. For an indoor padel court in an existing hall, whether a building permit is needed depends on the situation, but rules on fire safety and use apply there too. Never build without checking what is mandatory in your situation, because the municipality can shut down a project, impose fines or even require you to remove the cage structure.

The following documents are generally needed for the permit application:

• Structural calculations in accordance with the Dutch Building Decree (Bouwbesluit)
• Acoustic study
• Lighting study
• Site plan
• Sometimes also an ecological or archaeological survey

The lead time for a permit application averages 8 to 12 weeks, depending on the municipality and the complexity of the project. Take this into account in your planning. A permit can also be refused, for example if the zoning plan does not match or if noise standards are exceeded. In that case additional measures are needed, such as sound-absorbing panels or a noise barrier, before the application is submitted again.

After handover, the court must also be inspected for official matches by a recognised body. In the Netherlands that is Kiwa ISA Sport. All foundation components must meet their standards. Working with certified materials is therefore not a luxury, but a condition for preventing problems later.

At I-Padel we guide and coordinate the entire permit process, from the zoning plan check to the acoustic study and the structural calculations. Do you want to know what is needed in your situation?
