approach combining acoustics and aeraulics\u2014two inseparable disciplines in HVAC ductwork design. At F2A, we combine these areas of expertise to ensure optimal integration of acoustic equipment within ventilation systems, while maintaining the aeraulic performance of the installation.<\/p><p>For each HVAC acoustic study, our team relies on <strong>Aircoustic<\/strong>, a software tool developed by our acousticians and enhanced by over 25 years of experience in aeraulic acoustics. This calculation tool is based on recognized references in HVAC engineering and building acoustics, including <strong>ASHRAE guidelines, VDI 2081, and NF EN 12354-5<\/strong>, enabling precise modeling of noise propagation within ventilation systems.<\/p><p>Our expertise is based on a comprehensive analysis of the acoustic behavior of HVAC installations. We specifically study the <strong>sound power of equipment<\/strong>, the <strong>sound pressure levels actually perceived in occupied spaces<\/strong>, and the <strong>octave band spectrum distribution<\/strong> in order to identify critical frequencies. Noise propagation is modeled globally, taking into account the <strong>direct field<\/strong>, the <strong>reverberant field related to room reverberation time<\/strong>, the <strong>directivity factor of sources<\/strong>, as well as <strong>airborne and structure-borne transmission<\/strong> within ventilation systems.<\/p><p>Each project begins with a rigorous collection of technical data related to equipment and building architecture. We then carry out a complete modeling of the aeraulic network, including <strong>self-generated noise phenomena<\/strong> caused by bends, dampers, control devices, or diffusers, as well as the <strong>insertion loss of HVAC silencers<\/strong>.<\/p><p>The analysis of the most critical room finally allows us to accurately size <strong>acoustic treatment solutions by identifying the best compromise between acoustic attenuation, pressure losses, and aeraulic performance<\/strong>. This structured and comprehensive approach ensures measurable results, compliant with regulatory requirements and perfectly adapted to the real constraints of the installation.<\/p><p>The information you need to provide us for conducting an acoustic study:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a38dad7 e-con-full notre_expertise_section_table e-flex e-con e-child\" data-id=\"a38dad7\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6caa7a0 elementor-widget elementor-widget-html\" data-id=\"6caa7a0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t\t<div class=\"table-wrapper\">\n  <table class=\"elementor-data-table\">\n    <thead>\n      <tr>\n        <th>DATA TO BE PROVIDED<\/th>\n        <th>ELEMENTS CONCERNED<\/th>\n        <th>FORMATS<\/th>\n      <\/tr>\n    <\/thead>\n    <tbody>\n      <tr>\n        <td>Sound power spectra<\/td>\n        <td>\n          <span class=\"cell-label\">Air handling equipment:<\/span>\n          <ul>\n            <li>Air handling units (AHUs)<\/li>\n            <li>Fans<\/li>\n            <li>Chillers<\/li>\n          <\/ul>\n        <\/td>\n        <td>Octave band format<\/td>\n      <\/tr>\n      <tr>\n        <td>Acoustic characteristics<\/td>\n        <td>\n          <span class=\"cell-label\">Ductwork components:<\/span>\n          <ul>\n            <li>Dampers<\/li>\n            <li>Control dampers<\/li>\n            <li>Diffusers<\/li>\n            <li>Grilles<\/li>\n            <li>\u2026<\/li>\n          <\/ul>\n        <\/td>\n        <td>Octave band format<\/td>\n      <\/tr>\n      <tr>\n        <td>Airflow rates<\/td>\n        <td>Air handling units Served areas Diffusers<\/td>\n        <td>Octave band format<\/td>\n      <\/tr>\n      <tr>\n        <td>Drawings and sections<\/td>\n        <td>Floor plans Ductwork networks<\/td>\n        <td>DWG files<\/td>\n      <\/tr>\n      <tr>\n        <td>Acoustic targets<\/td>\n        <td>Acoustic specifications or technical requirements (CCTP)<\/td>\n        <td><\/td>\n      <\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-80c7ed1 e-con-full e-flex e-con e-child\" data-id=\"80c7ed1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-88b4bb7 elementor-widget elementor-widget-image\" data-id=\"88b4bb7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"25\" height=\"26\" src=\"https:\/\/f2a.fr\/wp-content\/uploads\/2026\/04\/2f1a9cc356a862220317e4bf0e9f2e2e.svg\" class=\"attachment-full size-full wp-image-25966\" alt=\"Red vertical line\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7534650 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"7534650\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Our industrial acoustic expertise: controlling equipment noise radiation<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-b487255 e-con-full e-flex e-con e-child\" data-id=\"b487255\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-747504f dynamic elementor-widget elementor-widget-text-editor\" data-id=\"747504f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>In addition to its expertise in aeraulic acoustics, F2A designs and develops <strong>custom acoustic enclosures<\/strong> aimed at effectively reducing noise emissions generated by technical and industrial equipment.<\/p><p>This acoustic enclosure solution makes it possible to contain noise sources while maintaining the operational performance of installations such as <strong>air handling units, fans, compressors, pumps, or industrial machinery.<\/strong><\/p><p>F2A acoustic enclosures are based on a <strong>modular and scalable design<\/strong>, allowing the solution to be adapted to the installation configuration and operational constraints.
