HOLOPLOT unique capabilities
HOLOPLOT technology is science-based, software-driven, and hardware-enabled. We aim to deliver a comprehensive, end-to-end solution enclosing an interconnected hardware and software ecosystem. This enhances workflow and fosters seamless interoperability among system designers, content creators, and operational staff, by ensuring a consistent and efficient experience across all stages of sound, system design, deployment, and use.
One of the biggest limitations of conventional loudspeaker technology is the lack, or, limited control over sound propagation, leading to undirected sound waves, disturbing reflections, reverberations, and an inconsistent sound experience across the audience area.
HOLOPLOT 3D Audio-Beamforming technology allows you to steer sound and place it precisely where you want it by providing directivity control in both the vertical and horizontal axes. This allows for the creation of sound fields that optimally cover audience areas of any shape and size.
The HOLOPLOT Beam Optimization Algorithms ensure uniform coverage and consistent sound quality across the entire audience area, making every seat the best seat. With the high-resolution control of individually driven transducers per array, the sound level and frequency distribution are finely adjusted for optimal uniformity, significantly reducing the need for extensive commissioning and tuning.
Constant SPL and STI
HOLOPLOT Matrix Arrays produce parallel wavefronts, also known as plane waves, that are flat, parallel, and travel in a single direction. In theory, the level across the direction of propagation is constant, although air absorption and other physical effects minimally affect the level over distance in practice.
In applications where speech intelligibility is the main design criterion, a system like HOLOPLOT presents several unique selling points (USPs) that, by themselves or in combination, increase the Speech Transmission Index (STI).
HOLOPLOT ensures that sound is evenly distributed across the entire audience area, avoiding hotspots and dead zones, and maintaining a consistent level and frequency response throughout. By tailoring the sound beam to the shape of the audience area, the system reduces unwanted reflections and reverberation, greatly enhancing Speech Transmission Index (STI).
Multiple content zones from a single array
A single HOLOPLOT Matrix Array can simultaneously produce multiple sound fields (whether generated using 3D Audio-Beamforming or Wave Field Synthesis) with their own content, equalization, level, and shape.
With 3D Audio-Beamforming, we can create multiple distinct sound zones, allowing different venue areas to receive different audio content. Leveraging the advantages of HOLOPLOT's cloud-based optimization engine, each beam's coverage, level, and spectral homogeneity are optimized for every zone while minimizing sound spill between zones. This ensures precise and clear audio delivery tailored to each specific area.
This unique feature provides excellent value in functional applications and unprecedented creative potential to utilize a space for multiple different experiences.
Focused content and targeted experiences
HOLOPLOT's 3D Audio-Beamforming and Wave Field Synthesis technologies enable the creation of complex, immersive audio experiences. By utilizing Virtual Sources positioned in front of the array or small Coverage Beams, sound fields can be precisely targeted to specific locations within the venue, delivering tailored audio experiences to small groups or even individual audience members. The audio they hear will vary depending on their location in the venue.
This advanced capability offers a significantly broader creative sonic palette compared to traditional loudspeaker systems, allowing for the design of soundscapes that enable listeners to embark on an explorative auditory journey and feel fully immersed in the experience.
Concealment
HOLOPLOT products blend effortlessly into their surroundings without compromising on performance. Our arrays can be fully hidden behind fabric, acoustically transparent carbon fiber panels, or LED screens.
Using 3D Audio-Beamforming to direct sound energy, the array can be flat or tilted with the screen, allowing for seamless architectural integration.
Proprietary compensation algorithms retain the characteristic clarity of sound of X1 by compensating for the angle-dependent and frequency-dependent transmission loss created by an obstructing screen. The effects can be described similarly to those of a directional-dependent, spatial EQ.
The straight shape of a Matrix Array arrangement keeps all sound sources (drivers) at a constant distance from an LED screen structure. As a result, the transmission loss in a certain direction is the same for all drivers, allowing a uniform compensation across the array.
HOLOPLOT offers the option of applying a custom 3D compensation FIR filter to each loudspeaker to enhance the performance of the arrays behind a projection panel or LED screen.
Reflections and virtual acoustics
Virtual Sources enhance sound distribution and create immersive audio experiences. By using 3D Audio-Beamforming or focussed Virtual Sources, HOLOPLOT arrays can concentrate acoustic energy at specific reflective surfaces within a venue. This controlled redirection of sound waves enables the system to actively excite areas that otherwise pose a challenge to the system's performance.
Virtual Sources can add a layer of creativity to the system and show design. By carefully designing these reflections to arrive from different directions compared to the direct sound from the array, the illusion can be created that sound emanates from various surfaces around the venue. This technique can enhance the sense of envelopment and depth, making the sound feel more natural and immersive. For instance, Virtual Sources can contribute to the early reflections or reverberation to simulate the acoustics of a grander, more resonant space, enriching the overall experience for the audience.
Overcoming poor room acoustics and minimizing reverb
Excessive reverberation can blur speech intelligibility and degrade audio quality in spaces with challenging acoustics. HOLOPLOT’s technology addresses this by directing sound waves to precisely where they are needed, minimizing interactions with reflective surfaces that could cause unwanted reflections and echoes. The system’s ability to create highly directional beams means that energy is focused on the audience rather than dispersing throughout the room, significantly reducing the chances of sound bouncing off walls, ceilings, and other surfaces.
This adaptability ensures that the audio remains clear and intelligible even in rooms with poor acoustics. Compared to traditional acoustic treatment, this comprehensive approach to managing room acoustics and reverb demonstrates HOLOPLOT’s capability to transform suboptimal spaces into venues with exceptional sound quality.
Digitally programmable
HOLOPLOT's digitally programmable nature offers significant advantages in terms of flexibility and precision. The system can be configured and adjusted via software, allowing for real-time preset changes that adapt to new venue conditions or use cases without the need for physical reconfiguration of the system. This flexibility is highly beneficial for venues that host different types of events, each requiring different acoustic settings. By simply loading a different preset configuration, a concert hall can seamlessly transition from an optimal setup for a classical music performance to one suitable for a rock concert or a speech. This adaptability saves time and resources and ensures that the audio experience is always tailored to the specific requirements of each event for optimal sonic results. HOLOPLOT software updates continually enhance system performance and introduce new features. This ongoing improvement and adaptability underscore the significant advantages of a digitally programmable sound system in delivering superior and consistent audio experiences.
Reduce noise breakouts
A HOLOPLOT system significantly reduces noise and improves noise pollution, important concerns in urban areas and multi-purpose venues. The system uses advanced 3D Audio-Beamforming technology to direct sound exactly where it's needed, minimizing the spread of sound into surrounding areas. By concentrating the acoustic energy on the audience area and avoiding unnecessary dispersion, HOLOPLOT reduces the amount of sound that escapes the intended zone, preventing noise from reaching neighboring spaces. This precise control is especially useful in places like theaters, conference centers, and mixed-use buildings, where different activities occur simultaneously and maintaining sound isolation is crucial.
Furthermore, HOLOPLOT's capability to create directed and tailored beams for specific audiences also helps in decreasing overall noise pollution. HOLOPLOT arrays benefit from the baffle effect, which effectively reduces the rear radiation of mid to low-mid frequencies. This effect is achieved by stacking Audio Modules horizontally and vertically, increasing the dimensions of the array which blocks sound that would otherwise radiate backwards. As a result, the rear sound energy is significantly reduced, preventing it from contributing to noise pollution in areas behind the speakers. This dual advantage of precise beamforming and reduced rear radiation ensures that HOLOPLOT systems deliver high-quality sound to the intended audience while minimizing the acoustic impact on the surrounding environment. This enhances overall noise management and compliance with noise control regulations.
