Electric vehicles, including Teslas, are known for their quiet operation. However, this can pose a safety risk as pedestrians may not hear an approaching car. To address this, Tesla has introduced a Pedestrian Warning System, also known as a low-speed sound emitter, which emits a sound when the car is driving below a certain speed or in reverse. This system is designed to alert pedestrians to the presence of the vehicle, especially in urban areas with high foot traffic. While some Tesla owners find this feature annoying and unnecessary, others appreciate the ability to customize their engine noise through software updates, simulating the sound of a Porsche, Ferrari, or even a V8 engine.

The Pedestrian Warning System
Electric vehicles, including Teslas, are known for their quiet operation. However, this lack of engine noise can pose a safety risk to pedestrians, especially in urban areas. To address this issue, Tesla has introduced the Pedestrian Warning System (PWS), also known as a low-speed sound emitter, in its vehicles.
The availability of the Pedestrian Warning System in Tesla vehicles may depend on the manufacturing date. Vehicles manufactured before a certain date, such as September 1, 2020, may not have this feature. It's important to note that even with the PWS, drivers should not solely rely on it to ensure that pedestrians are aware of their vehicle. Other factors, such as road noise and wind buffeting, can also affect the audibility of the warning sound.
In addition to the Pedestrian Warning System, Tesla allows its drivers to customize their driving experience with various sound options. For example, Tesla owners can simulate different engine sounds, such as a V8 engine, a Porsche, or a Ferrari, through external speakers. These simulated engine noises can be activated through the Toybox menu and the Boombox option. However, some Tesla drivers find these simulated engine noises unnecessary or annoying and prefer the quiet operation of their electric vehicles.

Fake engine noises
Electric vehicles are typically silent, but some consumers dislike the lack of engine noise. Manufacturers have responded by introducing artificial engine noise systems, which direct engine noise into the cabin or amplify it through the audio system. These systems are designed to replicate the driving experience of older vehicles with lower sound insulation.
Volkswagen's Soundaktor system, introduced in 2011, is one such example. It involves a speaker mounted between the engine and the cabin, which adds a "buzzy, fizzy noise" to the cabin. However, Volkswagen claims that this noise is not a digital recording but a reproduction of the car's actual engine noise. Other manufacturers, like BMW and Ford, have also been known to use artificial engine noise systems.
Tesla, an electric vehicle manufacturer, has also incorporated sound emitters into some of its models. The Model S Plaid, for instance, emits the sound of a large V8 engine through its external speakers. These speakers were added to meet requirements in certain markets for electric vehicles to make noise and to alert visually impaired individuals. While some consumers appreciate these fake engine noises, others find them annoying and unnecessary.
Some Tesla models also feature a low-speed sound emitter, which makes a noticeable noise when driving in reverse. This feature has sparked mixed reactions, with some users seeking ways to disable it. It is worth noting that while some view these sounds as "fake," they may be reproducing the actual engine noise of the vehicle.

Speakers and software
Tesla has a stock audio system that is considered to be of high quality. The Model 3, for example, comes with 11 speakers. The company hired former Bang & Olufsen engineers to design a system for each model, resulting in an audiophile flavour that discriminating listeners enjoy. The system is also excellent for gaming and watching movies.
In addition to the speakers, Tesla has a sound emitter known as the Pedestrian Warning System (PWS), which serves an important safety purpose. This system emits a sound when the car is driving below a certain speed (approximately 19 mph or 32 km/h for the Model Y, and 40 km/h for the Model 3) or when it is in reverse. The volume increases as the speed increases. Electric vehicles tend to operate quietly, so this sound helps to alert pedestrians to the presence of the approaching vehicle, especially in urban areas.
Tesla also has a feature that allows drivers to simulate engine sounds like those of a Porsche, Ferrari, Lamborghini, or even a jet, using the speaker system and software. This feature is accessible through the Toybox menu, where drivers can select the Boombox option and choose their desired engine sound.
Furthermore, Tesla started fitting hidden external speakers to its cars in September 2019 to meet the requirements in certain markets for electric vehicles to emit noise. The Model S Plaid, for example, can emit the sound of a V8 engine through these external speakers, designed to alert visually impaired individuals.

Customisation options
Tesla has a sound emitter known as the Pedestrian Warning System (PWS), which serves an important safety function. This system emits a sound when the car is driving below approximately 19 mph (30-40 km/h) or when it is in reverse. The volume of the sound increases as the speed of the car increases, providing a clear warning to those nearby. This feature is especially useful in urban areas with many pedestrians.
The PWS was introduced to meet requirements in certain markets for electric vehicles to emit noise. Electric vehicles are known for their quiet operation, which can be advantageous for some drivers, but it also means that pedestrians may not hear an oncoming vehicle, increasing the risk of collisions.
While some drivers appreciate the PWS for its safety benefits, others find it annoying and unnecessary, particularly as it cannot be customised. However, there are ways to disable or modify the sound emitter, although this may have insurance implications in the event of a mishap.
In addition to the PWS, Tesla offers a range of customisation options for its sound system, allowing drivers to personalise their driving experience. For example, drivers can adjust the volume and sound settings in the Model 3 audio settings, including a speed-sensitive volume feature that increases the volume as the car accelerates and lowers it when decelerating or stopping.
Tesla has also introduced the ability to customise the fake engine noise through an over-the-air software update. This feature allows owners to simulate the engine sound of a real gasoline sports car, such as a Porsche, Ferrari, or Lamborghini, using the speaker system and software. This simulation can be accessed through the Toybox menu by selecting the Boombox option and adjusting the Driving Sound slider.
Furthermore, Tesla has hired former Bang & Olufsen engineers to design a high-quality audio system for each model, enhancing the overall audio experience for drivers and passengers alike.

Safety and insurance
Electric vehicles, including Teslas, are known for their quiet operation. However, this lack of engine noise can pose a safety risk to pedestrians, especially in urban areas or when the car is reversing. To address this issue, Tesla has introduced a Pedestrian Warning System (PWS), also known as a low-speed sound emitter, in some of its models. This system emits a sound when the car is driving below a certain speed (approximately 19 mph or 32 km/h for the Model Y, and 40 km/h for the Model 3) or when it is in reverse. The volume of the sound increases as the speed of the car increases, providing a clear warning to nearby pedestrians.
The PWS is designed to reduce the risk of collisions and serious injuries caused by quiet electric vehicles. In fact, the National Highway Traffic Safety Administration (NHTSA) has mandated that all electric vehicles, including Teslas, must produce a fake engine noise at low speeds to alert pedestrians of their presence. This requirement is particularly important for visually impaired individuals who rely on sound to navigate their surroundings.
While some Tesla owners appreciate the added safety feature of the PWS, others find it annoying and unnecessary. Some have even considered disabling the system or choosing older Tesla models that do not have this feature. However, it is important to note that disabling the PWS could have insurance implications in the event of a mishap involving a pedestrian.
To comply with regulations and ensure the safety of pedestrians, Tesla has taken steps to implement code that validates the connection of the speaker for the PWS. Additionally, Tesla offers customization options for the engine noise through its Toybox menu, allowing owners to select from various sounds, including a V8 engine, a Porsche, a Ferrari, or a Lamborghini. These features not only enhance safety but also provide a unique audio experience for drivers and those around them.
