Acoustic Ecology & Safety

The purpose of the Thor Acoustic Vehicle Alerting System (AVAS) is to take road safety to the next level by helping to warn all participants of the approaching electric vehicle in 5 seconds, regardless of its speed.

City

Safety is the future. And our goal is not just to create a project of a street crowded with vehicles powered by electricity or alternative fuels only but to make it real.

We’re focused on acknowledging and improving the acoustic ecology in order to lower the risks of crashes linked to soundless electric transport.

According to EU Safety Requirement (UN 138 legislation), the acoustic alerting system must be activated at speeds up to 20 km/h, in the USA up to 31 km/h.

AVAS is an accessory required for electric cars in many countries. Many also refer to it as a pedestrian alarm, acoustic warning system, or pedestrian safety system. It offers a safety feature that can be added to any electric vehicles, including micromobility vehicles: electric mopeds, e-scooters; and huge ones such as electric buses and trucks.

The AVAS system provides audible warnings for otherwise silent electric cars to increase the safety of Vulnerable Road Users (VRU), as well as the vehicle's audible presence in low-speed traffic.

Thor AVAS tests

Our research aims to increase the level of acoustic safety: we observe how far a pedestrian should hear different types of electric vehicles; we select such sound frequencies that are the most recognizable and inherent in human hearing.

We provide multiple research for each sound, taking into account all environmental factors: time of day, location, background noise level.

Thor AVAS are pioneers in the acoustic safety of micromobility

We conduct psychoacoustic studies to understand the sound itself

We comprehensively cover the problem of electric vehicles' low noise

Thor AVAS sounds

We have collected Thor AVAS sounds that are already ringing on the streets. Each sound is multiply tested, unique, and created for a special transport type. You can use one of those or we can help you to create a new one based on your demand.

electric vehicles with our sounds are already on the streets of your cities

Thor AVAS uses bass 80-200 Hz that is pleasant and easy to perceive for every road user and can be easily heard in the city background (1000-3000Hz).
Frequencies that can be heard by a person (20-15000 Hz)
Frequencies of transport (600-1000 Hz)
