What are the layout skills of professional audio in the exhibition hall?

Installing a professional sound system in the exhibition hall is the key to ensuring sound quality and visitor experience. The following are some professional audio layout techniques in the exhibition hall:

1. Spatial analysis and acoustic positioning analysis of exhibition space: Understand the size, shape, layout, materials and possible echo points of the exhibition hall. Each space has its own unique acoustic characteristics, and understanding these characteristics is a prerequisite for effective use of the sound system. Determine sound location: Based on spatial analysis, determine the location of sound equipment, such as placement points for speakers and sound consoles, to achieve sound coverage and sound quality.

2. Reasonably arrange the speaker evenly along the moving line: according to the moving line of the exhibition hall, reasonably arrange the speaker on both sides or above it to ensure that the sound can evenly cover the walking route of visitors. Strengthening at key nodes: At key nodes such as entrances, exits, corners, and key display areas, appropriately increase the number of speaker or increase the power of the speaker to ensure that the sound can guide visitors to pay attention to the core display content.

3. Combine the theme and content of the exhibition. Sound matches the theme of the exhibition: ensure that sound is closely integrated with the content of the exhibition, highlight the theme, and deepen visitors 'impression of the exhibition. Choose the right sound effects and background music: Choose the right background music and sound effects according to the nature of the exhibition. For example, art galleries may require soft music, and technology exhibitions may require dynamic music and sound effects.

4. Consider acoustic characteristics to avoid echo and noise interference: Consider factors such as sound propagation, reflection and attenuation to avoid echo and noise interference. Sound-absorbing materials can be used to reduce echo interference. Adjust the height, angle and direction of the speaker: make the sound propagation direction consistent with the moving line, reduce loss and interference during sound propagation.

5. Humanized design and flexibility take into account visitors 'listening habits and comfort: the sound layout should consider factors such as moderate adjustment of volume and clear transmission of sound quality to ensure a high-quality listening experience at any time. Flexible adjustment and real-time monitoring: During the exhibition, the audio system is flexibly adjusted according to actual conditions. By monitoring the audio effects in real time, parameters such as volume and sound quality are adjusted in a timely manner.

6. Safety, reliability, environmental protection and energy conservation ensure the safe operation of equipment: Audio design should consider the safe operation of equipment to avoid accidents caused by problems such as overload and short circuits. Choose energy-saving and environmentally friendly equipment: While pursuing sound effects, we must also consider equipment energy consumption and choose energy-saving and environmentally friendly audio equipment.

When installing a professional sound system in an exhibition hall, avoiding echo and noise interference is the key to ensuring sound quality. Here are some effective strategies and techniques:

1. Reasonably arrange the location of audio equipment speaker: Reasonably select the location of audio equipment according to the spatial structure and layout of the exhibition hall. The main loudspeaker slightly should be placed in an area where the audience gathers, and the auxiliary slightly can be distributed in different corners of the exhibition hall to evenly cover the entire space. slightly height: Adjust the installation height of slightly. It is generally recommended to install the main sound reinforcement slightly at a position higher than the ground, such as on the ceiling, to use reflections from walls and ceilings to enhance sound effects and reduce echoes caused by direct reflections.

2. Use sound-absorbing materials and sound-absorbing panels: Install sound-absorbing panels, sound-absorbing bricks or sound-absorbing cloth and other materials on the walls, ceilings and floor of the exhibition hall to absorb excess sound waves and reduce echo and reverberation. Diffuser: Use an acoustic diffuser, such as a diffuser plate or diffuser device, to evenly disperse sound waves and avoid focusing and reflection of sound.

3. Sound insulation measures to control environmental noise: Install sound insulation materials, such as double glazing or sound insulation curtains, at the doors and windows of the exhibition hall to reduce the introduction of external noise. Internal noise control: Reasonably arrange the layout of equipment, avoid placing noise sources (such as air conditioners and ventilation systems) in areas where visitors often move, and regularly maintain equipment to reduce operating noise.

4. Debugging and optimizing your audio system Use audio processing software: Use audio processing software to perform automatic room corrections, adjust the frequency response of subwoofers and other speakers, optimize sound quality and reduce echo. Volume balance: Test the volume in different positions to ensure that the volume in each area of the exhibition hall is uniform and there is no obvious volume difference, so as to avoid excessive volume in some areas causing echoes.

5. Reasonably designed acoustic environment Acoustic isolation: Use soundproof walls, soundproof curtains or acoustic partitions to separate different areas to reduce sound cross-interference. Acoustic layout: Through reasonable exhibition layout and spatial planning, excessive concentration or interference of sound is avoided and uniform transmission of sound is ensured.
