Silentium Ltd. develops software-based Active Acoustics solutions designed to
manage in-cabin sound in vehicles. The Company’s technology reduces unwanted
noise, enhances desired audio cues, and enables personalized, configurable
acoustic experiences, thereby supporting improved comfort, safety, and perceived
quality in modern vehicles.
Silentium’s solutions are primarily deployed in the automotive market and are
designed to integrate with vehicle computing, control, and audio systems. Rather
than relying on heavy mechanical insulation or dedicated hardware modules, the
Company’s software leverages existing microphones, speakers, processors, and
electronic control units (ECUs) to monitor, estimate, and dynamically shape
acoustic fields inside the vehicle cabin. This software-centric approach aligns
with the automotive industry’s transition toward software-defined vehicle
architectures, in which functionality is increasingly implemented and updated
through software rather than fixed hardware components.
The Company works directly with automotive original equipment manufacturers that
design, engineer and produce vehicles under their own brands (“Auto OEMs”),
companies that supply complete systems and modules directly to Auto OEMs
(“Tier-1 suppliers”), and semiconductor and digital signal processing partners
to support adoption across vehicle platforms and production programs.
Silentium’s technology is typically embedded at the vehicle platform level and
remains integrated throughout the production lifecycle of the model, which
generally ranges from four to seven years.
Silentium is a development-stage company. To date, the Company’s commercialized
products consist exclusively of road noise and engine noise cancellation
solutions. As of May 31, 2026, Silentium’s technology was deployed in
approximately 1.8 million vehicles across 24 models of vehicles (each model as
defined by the applicable Auto OEM and collectively, “vehicle models”) and five
Auto OEMs. As additional vehicles enter production, the number of vehicles
incorporating our software increases, generating royalties over the production
life of each multi-year vehicle production cycle for which the Company provides
development services and per-unit royalty-bearing software licenses (“vehicle
program”), and enhancing revenue visibility.
Revenues are derived from non-recurring engineering (“NRE”) fees generated
during the software development and integration phases of specific vehicle
programs, followed by per-vehicle royalties that become payable upon the
commencement of serial production. Our royalty revenue depends on the Auto OEM’s
production volumes over the multi-year lifespan of the vehicle program. The
Company also integrates its algorithms into existing infotainment and audio
system architectures through Tier-1 suppliers and semiconductor manufacturers,
which can facilitate deployment across additional vehicle platforms.
Silentium operates globally, with its headquarters and principal research and
development activities based in Israel and additional engineering, technical
support and business development presence in North America, Europe and Asia.
This enables close collaboration with Auto OEMs and Tier-1 suppliers across
major automotive production hubs and supports ongoing program execution,
calibration, and validation activities.
While automotive remains the Company’s core focus, its Active Acoustic
Management (AAM) technology may also be applicable to other transportation and
mobility use cases, including rail, commercial vehicles, and heavy machinery,
where noise reduction, communication clarity, and acoustic zoning are relevant.
