EcoSilent Optimised Sound Design

ECO4, EcoSilent Optimised Sound Design

EcoSilent is a holistic approach to sound optimisation, which addresses both the reduction of exterior noise whilst harmonising interior sound to ensure comfort for passengers.

Low external noise emissions are ensured through optimised wheel and bogie designs, whilst sound emanating from electrical equipment and cooling systems is also minimised.

For the interior, Bombardier tackles the complex issue of creating a balanced acoustic environment by the use of a 'sound studio' concept in which a selection of design elements such as integrated absorbents, resonators, reflectors and intelligent material is fine-tuned and ensures all-round audio comfort for passengers.
