Silentium, which was founded in 1998, has raised $30 million as part of its Series D round, and approximately $63 million in total. The latest extended round was led by Menora Mivtachim and Meitav Dash, both Israeli institutional investors. Existing strategic investors, including global electronics leader Molex, also participated in this latest round.


Yoel Naor, CEO of Silentium, commented: “We welcome new partners that share the same passion for acoustics and see the value in enhancing privacy and wellbeing through personal sound spaces. With this new investment, we will scale up the development and roll-out of our Active Acoustics software solutions for vehicle manufacturers and automotive suppliers – especially as noise, vibration, and harshness (NVH) requirements evolve in the new era of electric and autonomous mobility.”


Silentium creates personal in-car sound environments by reducing, canceling, or enhancing any sound inside all types of vehicles. Since its recent launch into automotive, Silentium has been working on several global vehicle production programs for low-cost, flexible Active Road Noise Cancellation (ARNC) software integration. Already available in new cars including Jaguar and Land Rover, the broad-band ARNC technology works across an unprecedented spectrum of frequencies (20Hz up to 1kHz).


The company has 50 employees and is based outside Tel Aviv, it also has satellite offices around the world with sound engineers embedded within various global vehicle manufacturers. Within a year Silentium hopes to double its workforce.
