When is a noise barrier needed at padel courts?

Noise nuisance at padel courts is one of the most discussed topics among clubs, municipalities and operators who want to build a new court. The combination of racket, ball and glass walls produces a specific type of sound that carries further than many people expect. In this article we answer the most frequently asked questions about noise at padel courts: from how much noise a court produces to when a noise barrier or sound-absorbing panels are needed and what that costs.

How much noise does a padel court actually produce?

On average, a padel court produces a sound power level of around 91 dB. That is roughly 10 dB more than a tennis court. The difference lies not only in the ball being hit, but in the combination of factors that come together specifically in padel.

In tennis, the ball bounces back via an open racket on an open court. In padel, the ball hits glass walls and a steel cage structure. That cage acts as a sound box: the sound is amplified and reflected instead of absorbed. That makes padel a different sport from tennis acoustically, even though the courts look alike at first glance.

The noise consists of two components. First, the source noise of the racket hitting the ball. Second, the contact noise of the ball on glass and mesh. That second type of noise plays the biggest role in the nuisance experienced by local residents. It is a sharp, high-pitched and repeated sound that is clearly audible at a distance, even in calm weather.

When is a noise barrier or noise screen legally required?

A noise barrier or noise screen is not automatically legally required, but an acoustic study almost always is. Based on that study, the municipality determines whether additional measures are needed. For outdoor padel courts near residential buildings, there is a high chance that the municipality will make additional noise-reducing measures a condition for the environmental permit.

In the Netherlands, a padel court is regarded as a structure and falls under building regulations. An environmental permit is almost always required for outdoor courts. Part of that permit application is an acoustic study that demonstrates that the court complies with the noise standards for the surrounding area. Those standards depend on the zoning of the area: residential neighbourhood, sports zone or mixed area.

If the acoustic study shows that the noise standards are exceeded, you have to take measures. These can be sound-absorbing panels, a noise barrier or a combination of both. The municipality ultimately decides whether the proposed measures are sufficient. Building without a permit is not an option: the municipality can halt the project, impose fines or require the cage structure to be removed.

What is the difference between a noise barrier and sound-absorbing panels?

Sound-absorbing panels are placed directly on the outside of the padel court's cage structure and dampen the noise at the source. A noise barrier is a freestanding structure next to or around the court that blocks the sound further away, towards homes. The two solutions work differently and are not always interchangeable.

Sound-absorbing panels

Panels are attached to the mesh of the cage structure. They absorb the sound before it spreads into the surroundings, instead of reflecting it back. The court remains visually open and the dynamics of play do not change. Panels can be placed on one side, on several sides, or only on the lower or upper metres of the cage.

Noise barriers

A noise barrier is a bigger intervention. It is a freestanding, sound-blocking structure placed next to the court. Noise barriers can be up to 6 to 8 metres high and dozens of metres long. They are aimed at one specific direction where reduction is needed. Installation always requires a structural calculation, cone penetration test data and an environmental permit.

A combination of both

In many cases a combination of panels and a noise barrier is the most effective. The panels reduce the noise at the source, so the noise barrier can be lower. That saves costs and in some situations makes obtaining a permit easier.

Which locations most often have noise problems?

The locations that most often face noise problems are outdoor padel courts bordering residential neighbourhoods, courts on open sites without natural sound barriers and courts at tennis clubs located close to buildings. The combination of a high sound power level and little distance to homes is decisive.

Tennis clubs converting existing courts to padel courts experience this the most. A tennis club is often already in or near a residential area, and the switch from tennis to padel means a considerable increase in noise level. Residents who never complained about tennis sometimes do complain about padel.

Locations on open sites, coastal locations and sites with little surrounding development can also cause problems. Not because the distance to homes is small, but because sound carries further in open spaces. Wind amplifies this effect. At these kinds of locations an acoustic study is all the more relevant, even if the homes seem far away at first glance.

Indoor padel courts in existing halls generally cause less noise nuisance to the surroundings. The hall already dampens the sound considerably. Here noise nuisance more often plays a role internally, for example for adjacent spaces in the same building.

How do sound-absorbing panels work on a padel court?

Sound-absorbing panels work by absorbing the sound leaving the cage structure instead of reflecting it back. They are attached to the outside of the mesh and turn the hard, reflective surfaces of steel and mesh into sound-dampening material. Independent laboratory research shows that well-executed panels achieve an absorption value of αw 0.80, which corresponds to sound absorption class A.

In practice this results in a clearly audible noise reduction at distances of roughly 40 to 100 metres. The airborne sound insulation is Rw 22 dB, with a sound insulation index DLR of 19 dB. These are not theoretical figures: the difference is noticeable to local residents even without measuring equipment.

An important point that many people overlook: panels change the wind exposure of the cage structure. Mesh is wind-transparent. Panels are not. As a result, the wind load on the structure increases as soon as you install panels. The cage structure must therefore be structurally reinforced in line with the wind zone. This is not an optional step, but a safety requirement. Heavier posts, additional columns or modified connections depend on the location and the number of panels used.

Can a sound-absorbing solution also be added afterwards?

Yes, both sound-absorbing panels and noise barriers can also be added to existing padel courts afterwards. For panels, the existing cage structure must first be structurally assessed and in many cases reinforced. This is a technical step that must not be skipped.

For an existing court, the process starts with a structural assessment of the current steel structure. Based on that, it is determined whether and how the structure must be reinforced to absorb the extra wind load of the panels. Only then can the panels be installed. This applies both to panels on one side and to full enclosure.

Adding a noise barrier afterwards is technically simpler, because the barrier is a freestanding structure that has no connection to the existing court. Here too, however, a structural calculation, cone penetration test data and an environmental permit are needed. The processing time for a permit application averages 8 to 12 weeks, depending on the municipality and the complexity of the situation.

For existing courts at tennis clubs facing complaints from local residents, a combined approach is often the quickest route to a solution: panels dampen the noise at the source, and a noise barrier catches the remaining noise heading towards the homes.

What does a noise solution for a padel court cost?

The cost of a noise solution varies widely, depending on the chosen approach, the number of courts, the location and the scale of the intervention. For sound-absorbing panels, the price as a guide depends on the number of sides to be fitted with panels and the structural reinforcement required. A noise barrier is in most cases a larger investment because of its size and the foundation requirements.

Whatever the exact price, the cost of a noise solution is almost always lower than the cost of a failed permit process, a forced demolition or a prolonged conflict with local residents. Investing in a good noise solution up front prevents much bigger problems later.

The following factors determine the cost calculation:

• The number of sides on which panels are installed
• The height of the cage structure and the number of metres to be treated
• The structural reinforcement of the steel structure that is required
• Whether a noise barrier is needed and how high and long it must be
• The soil conditions and accessibility of the location for a noise barrier
• Whether it concerns a new court or an existing situation

All foundation components used for a noise barrier must be approved by Kiwa ISA Sport in the Netherlands. Working with certified materials is not only a quality choice, but also a requirement for obtaining an environmental permit and for official competition use. This is something to pay close attention to when choosing a supplier.

At I-Padel we calculate every noise solution per location. We look at the specific situation, the wind zone, the position relative to homes and the wishes of the client. That way we arrive at a solution that is technically sound, fits within the permit process and is realistically priced. Want to know what a noise solution for your location costs?
