Applications
Hearing, as one of the fundamental human senses, has inspired the development of sciences aimed at fulfilling human needs and realizing innovative ideas for improved auditory experiences.
Throughout humanity’s pursuit of this goal, physicists established the science of acoustics, which studies the behavior of sound waves in physical environments. In parallel, electronic engineers developed methods to convert acoustic waves into electrical signals, enabling their transmission from one location to another.
The integration of these disciplines led to the emergence of electro-acoustics. Audio engineers, as pioneers in this field, are responsible for designing and implementing advanced electroacoustic and sound systems, drawing on expertise in electronics (signal processing and amplification), acoustics (sound physics and wave behavior), equipment, and environmental considerations.
Pajoohesh Gostaran Navaye Nik Company is proud to be one of innovative integration companies of audio and electro-acoustic systems.
The Research and Development Department of Pajoohesh Gostaran Navaye Nik, following a structured program, designs and manufactures high-power sound sources with exceptional acoustic performance and durable, high-quality materials, offering competitive advantages over international models.
All products are custom-designed and acoustically optimized based on the specific requirements and environmental conditions of each project, ensuring maximum efficiency and performance.
Current production focuses on solutions for demanding acoustic environments, including sports stadiums, large halls, horn-loaded loudspeaker systems, and column array installations.
- Optimized acoustic directivity for challenging environments, ensuring controlled sound dispersion and maximum intelligibility for listeners.
- Robust construction using high-quality acoustic materials, designed to withstand impact, dust, and harsh environmental conditions.
- High sound pressure levels (SPL), enabling powerful and clear sound projection over long distances.
- Fully customizable solutions, tailored to the technical and operational requirements of each client.
Holding business meetings, seminars, and conferences requires high-quality audio-visual equipment in acoustically optimized spaces. Conference systems provide features such as recording, playback, voting, simultaneous interpretation, and documentation, and can be implemented either wired or wireless, depending on your specific needs.
With over a decade of experience, Pajohesh Gostaran Navaye Nik designs and implements professional conference systems using reliable, high-quality equipment, tailored to meet project requirements and budget constraints.
Step 1: Information Gathering
Step 2: Software-Based System Design
Step 3: Proposal Presentation
Step 4: System Implementation
Listening quality in office, educational, and cultural spaces depends on proper acoustic design. Common construction materials often provide poor sound absorption and allow excessive sound transmission, resulting in noise and unwanted reverberation.
To control reverberation time and reduce sound transmission, engineers develop solutions based on acoustic measurements and simulations. Following analysis and coordination with architects, these solutions are translated into detailed design plans and implementation strategies.
Step 1 : Acoustic data collection and on-site measurements
Step 2 : Acoustic simulation based on collected data
Step 3 : Acoustic treatment design and material selection
Step 4 : Implementation and system installation
In certain spaces, sound quality is directly influenced by the acoustic conditions of the environment, and even the most advanced audio systems cannot deliver satisfactory results in poorly designed acoustic settings.
At Pajoohesh Gostaran Navaye Nik, we specialize in designing systems that ensure clear, high-quality sound by providing comprehensive acoustic and electro-acoustic solutions.
One of the most critical parameters in acoustic space design is reverberation time. Excessive reverberation reduces speech intelligibility, while insufficient reverberation can result in an acoustically unsuitable environment. Achieving optimal performance requires a precise balance of these parameters.
Step 1: Perform acoustic calculations and determine appropriate acoustic materials.
Step 2: Conduct acoustic simulations based on collected data to ensure design accuracy.
Step 3: Provide detailed execution drawings.
Step 4: Implement solutions and address potential challenges during the installation process.
Step 5: Perform on-site acoustic measurements and final testing at project delivery.
Solutions for Public Address and Evac systems
Public Address (PA) systems are designed to broadcast voice messages and warning announcements in public environments such as airports, shopping malls, hospitals, cultural centers, and transportation hubs. When integrated with fire alarm systems, these solutions play a critical role in safety, security, and crisis management.
Accurate sound source selection: Errors at this stage are often irreversible during installation.
Correct system architecture: Proper component placement ensures performance and future expandability.
Ease of use and maintenance: User-friendly design and customization are essential for stable and reliable operation.
Standards compliance: Designing in accordance with current standards guarantees system quality and safety.
Pajoohesh Gostaran Navaye Nik is a knowledge-based company with a solid background in professional audio-visual systems. Building on this expertise, we have strategically expanded into Artificial Intelligence to develop advanced, data-driven solutions for complex acoustic and visual environments.
Our ongoing research and development activities focus on AI-based environmental sound analysis, intelligent sound classification, noise pollution assessment, sound source localization, and the fusion of audio and visual data using multimodal AI approaches. By integrating state-of-the-art machine learning, signal processing, and audio-visual fusion techniques, we aim to create intelligent systems capable of accurate perception and analysis of real-world environments.
Solutions for Video and Image Systems
Professional imaging systems are used to create visual experiences and deliver content across a wide range of applications, including cultural, religious, educational, tourism, and other environments.
To ensure the proper performance of imaging systems, careful attention must be given to key parameters such as ANSI lumens, resolution, throw ratio, contrast ratio, and aspect ratio. These factors should be selected based on the size of the installation space, ambient lighting conditions, projection distance, and audience requirements.
One of the most critical factors influencing image quality and brightness in projection systems is the level of ambient light. Depending on the application and environmental lighting conditions, selecting the appropriate type of projector is essential to achieving optimal visual performance.
Video mapping is a display technology that can project videos, animations, and other special visual effects onto three-dimensional or two-dimensional objects. These objects can range in size from small items, such as a birthday cake, to large-scale structures, like historical monuments.
Video mapping is created using specialized software that maps images precisely onto objects and buildings, enhancing the visual impact of shows, events, or advertising campaigns. For an even greater effect, video mapping is often synchronized with music to create an immersive experience.
Solutions for Professional Lighting Systems
Designing professional lighting systems for concerts, conferences, cinemas, and amphitheaters plays a crucial role in shaping the audience’s visual experience and overall satisfaction.
During the design process, key lighting parameters such as intensity, color, and reflection must be carefully considered. Improperly designed or non-standard lighting can lead to discomfort, visual fatigue, or other negative effects on participants and audiences.
One of the most critical factors in lighting design is the Color Rendering Index (CRI). High-CRI lighting ensures accurate color reproduction, enhancing visual clarity and realism—an essential requirement for professional stages and performance environments.
Professional lighting systems combine advanced projectors and searchlights strategically placed around the venue to create stunning visual effects for stages and halls. Our solutions include PAR lights, floodlights, spotlights, and moving heads, designed to transform any performance or event into an unforgettable experience.
