Whether it&#8217;s a conference, a concert, a play, or a ceremony, the sound must be clear, crisp, and balanced so that the audience can enjoy and appreciate the content.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A good sound system in auditoriums not only improves audio quality but also enhances the audience&#8217;s experience and the success of the event. Quality sound enables effective message delivery, captures the audience&#8217;s attention and interest, generates positive emotions and sensations, and fosters participation and feedback.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this article, we will explain how to design, install, and maintain an auditorium sound system that meets your expectations and needs. We will cover the <a href=\"https:\/\/schallertech.com\/sonido-profesional-para-iglesias-pequenas\/\"  data-wpil-monitor-id=\"832\">key elements of a sound<\/a> system, the acoustic characteristics of the auditorium, and recommendations for optimizing sound quality.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Auditorium Acoustic Design<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The <a href=\"https:\/\/schallertech.com\/en\/all-about-auditorium-design-architecture-acoustics-technology-and-furniture\/\">auditorium&#8217;s acoustic design<\/a> is the process of adapting the physical space of the auditorium for optimal sound conditions. Acoustic design impacts sound quality by determining how sound propagates, reflects, and is absorbed within the auditorium.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A good acoustic design should consider the type of event being held, the number and distribution of attendees, ambient noise levels, and the features of the sound system. The goal is to achieve consistent, intelligible, and pleasant sound throughout the auditorium.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Auditorium Acoustic Characteristics<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The auditorium&#8217;s acoustic characteristics are parameters that define the acoustic quality of the space. Some of the most important acoustic characteristics include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Sound level: this is the intensity or volume of sound perceived in the auditorium. It depends on the power of the sound system, the distance between sound sources and receivers, and the absorption or reflection of sound by the auditorium&#8217;s surfaces.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Sound energy distribution: this is how sound spreads throughout the auditorium. It depends on the location and orientation of the sound sources (speakers) and receivers (attendees) and the shape and <a href=\"https:\/\/schallertech.com\/en\/types-features-and-recommended-sizes-for-auditoriums\/\">size of the auditorium<\/a>.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Reverberation time: this is the time it takes for sound to decrease by 60 decibels after the sound source has stopped. It depends on the absorption or reflection of sound by the auditorium&#8217;s surfaces. An appropriate reverberation time should allow for good speech intelligibility and a pleasant musical sensation.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Acoustic defects: these are phenomena that degrade the acoustic quality of the auditorium. Examples include echoes, late reflections, sound concentrations, resonances, external or internal noise, etc.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">Recommendations for Improving Auditorium Acoustics<\/span><\/h3>\n<p><img decoding=\"async\" class=\"size-full wp-image-1783 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/Proyecto-Auditorio-Carlos-Corredor-Universidad-Simon-Bolivar.-Durante-la-intervencion-acustica-1-e1684599076623.jpeg\" alt=\"Carlos Corredor Auditorium Project at Sim\u00f3n Bol\u00edvar University.

Absorbent materials reduce the sound level and the reverberation time by dissipating the sound energy. Some examples are carpets, <a href=\"https:\/\/schallertech.com\/en\/how-to-choose-the-right-acoustic-panels-for-your-space\/\">acoustic panels<\/a>, or acoustic foam. Reflective materials increase the sound level and the reverberation time by returning the sound energy. Some examples are wood, metal, or glass.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Placing diffusing or scattering sound elements on reflective surfaces to avoid undesirable concentrations or reflections. Diffusing elements can be decorative or architectural objects that have irregular or curved shapes that scatter the sound in different directions.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Installing a modular false ceiling with acoustic treatment to improve the distribution and uniformity of sound in the auditorium. The false ceiling is a structure suspended below the original ceiling that allows the placement of technical equipment such as speakers, lights, or ventilation systems. The acoustic treatment may consist of absorbent or reflective panels as appropriate.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">The Key Elements of a Sound System for Auditoriums<\/span><\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1634 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1.jpg\" alt=\"Sound in auditoriums\" width=\"799\" height=\"533\" title=\"\"><noscript><img decoding=\"async\" class=\"aligncenter size-full wp-image-1634 lazyload\" src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1.jpg\" alt=\"Sound in auditoriums\" width=\"799\" height=\"533\" title=\"\" srcset=\"https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-200x133.jpg 200w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-300x200.jpg 300w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-400x267.jpg 400w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-500x334.jpg 500w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-600x400.jpg 600w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-700x467.jpg 700w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1-768x512.jpg 768w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/44898669635_ba535294ec_c-1.jpg 799w\" sizes=\"(max-width: 799px) 100vw, 799px\" \/><\/noscript><\/p>\n<p><span style=\"font-weight: 400;\">A sound system for auditoriums is the set of electronic equipment that allows capturing, processing, amplifying, and reproducing sound in an auditorium.

They are the most faithful and linear but also the least efficient and hottest.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Class B: amplify the signal in alternate parts, clipping the negative or positive part. They are more efficient and cooler than Class A but also more distorted and noisy.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Class AB: combine the characteristics of Class A and B, amplifying the entire signal with slight distortion. They strike a balance between fidelity and efficiency.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Class D: convert the analog signal into digital using pulse modulation. They are the most efficient and coolest but also the most complex and prone to interference.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Choosing the appropriate type of amplifier depends on the type and power of the speakers, the desired quality, and the available budget.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The correct connection of the amplifier requires following technical specifications and safety standards. Some general recommendations for connecting the amplifier are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Connect the mixer output to the amplifier input using balanced cables to avoid noise and interference.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Connect the amplifier output to the speaker input using cables appropriate to the type and power of the speakers.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Adjust the impedance (electrical resistance) of the amplifier to match the impedance of the speakers to prevent damage or losses in sound.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Adjust the gain (level) of the amplifier to the optimal level without exceeding the maximum limit to avoid saturation or distortion in sound.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">How to Design a Sound System for Auditoriums<\/span><\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1635 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1.jpg\" alt=\"Audio in auditorium\" width=\"799\" height=\"533\" title=\"\"><noscript><img decoding=\"async\" class=\"aligncenter size-full wp-image-1635 lazyload\" src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1.jpg\" alt=\"Audio in auditorium\" width=\"799\" height=\"533\" title=\"\" srcset=\"https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-200x133.jpg 200w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-300x200.jpg 300w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-400x267.jpg 400w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-500x334.jpg 500w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-600x400.jpg 600w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-700x467.jpg 700w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1-768x512.jpg 768w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/45811916051_6c8e021a26_c-1.jpg 799w\" sizes=\"(max-width: 799px) 100vw, 799px\" \/><\/noscript><\/p>\n<p><span style=\"font-weight: 400;\">Designing a sound system for auditoriums is a complex task that requires planning, knowledge, and creativity.

Some examples are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Interferences: are alterations or distortions of the sound caused by the presence of other electrical or electromagnetic signals. These can be avoided by using shielded or screened cables, separating equipment that generates interference, or using different frequencies.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Unwanted noise: are unwanted sounds that mix with the main sound. These can be external (coming from the environment) or internal (coming from the equipment). These can be avoided by using directional microphones, placing the equipment away from noise sources, or using noise filters or suppressors.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Distortions: are deformations or alterations of the original sound. These can be harmonic (changes in tone) or non-harmonic (changes in the waveform). These can be avoided by using quality equipment, correctly adjusting levels, and properly equalizing the sound.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Feedbacks: are sound loops or feedback that occur when the sound reproduced by the speakers is captured by the microphones and amplified again. These can be avoided by placing microphones away from speakers, orienting speakers towards the audience and not towards the stage, reducing the level or gain of microphones, or using feedback filters or suppressors.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Short Circuits: These are electrical faults that occur when there is improper contact between two conductors with different electrical potential. They can be avoided by using cables in good condition, correctly connecting equipment according to their polarity, and protecting the equipment from moisture or heat.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">Maintenance and Upgrade of the Sound System<\/span><\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1636 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1.jpg\" alt=\"Sounds in auditoriums\" width=\"799\" height=\"533\" title=\"\"><noscript><img decoding=\"async\" class=\"aligncenter size-full wp-image-1636 lazyload\" src=\"http:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1.jpg\" alt=\"Sounds in auditoriums\" width=\"799\" height=\"533\" title=\"\" srcset=\"https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-200x133.jpg 200w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-300x200.jpg 300w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-400x267.jpg 400w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-500x334.jpg 500w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-600x400.jpg 600w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-700x467.jpg 700w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1-768x512.jpg 768w, https:\/\/schallertech.com\/wp-content\/uploads\/2023\/05\/42173398041_c5800bd2c6_c-1.jpg 799w\" sizes=\"(max-width: 799px) 100vw, 799px\" \/><\/noscript><\/p>\n<p><span style=\"font-weight: 400;\">We are a leading company in auditorium sound systems with over 20 years of experience in the industry, having successfully completed a large number of projects.
