In the home, it is also a sound source that starts, stops and changes character throughout the day. In a quiet kitchen or an open living space, a low hum, a tonal fan sound or a short vibration at compressor start-up can become surprisingly noticeable. As wine coolers move closer to where people live, eat and relax, silence stops being just the absence of sound and becomes part of the comfort and quality the user actually experiences.<\/strong><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">This is not only a design consideration. Under the EU energy labelling framework for refrigerating appliances, including dedicated wine storage units, manufacturers must declare airborne acoustic noise emissions (in dB(A)) and a noise emission class (A\u2013D) on the energy label. That gives acoustic performance a second reason to be treated as a design parameter from the outset, rather than a final troubleshooting exercise.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_heading\">\n<h4 id=\"h-where-does-wine-cooler-noise-come-from\" class=\"wp-block-heading\">Where does wine cooler noise come from?<\/h4>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">The exact noise profile depends on the cooling architecture, component selection and cabinet design, but most compressor-based wine coolers share a few common sources.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"block-media-embed overflow-hidden pt-6 md:pt-6 lg:pt-6 pb-6 md:pb-6 lg:pb-6 theme- schema-bg-color-default\"\n     id=\"block_6abf8f4f5052b\">\n\n    <div class=\"container mx-auto px-4 lg:px-4 relative\">\n        <div class=\"lg:mx-auto max-w-2xl\">\n\n            \n            \n            <div class=\"w-full flex flex-col items-center justify-center\">\n\n                \n    <div class=\"overflow-hidden rounded shadow-lg\">\n                    <a href=\"https:\/\/bpi.dk\/wp-content\/uploads\/2026\/09\/Wine-Cooler-Visuals-1.png\" data-vbtype=\"\" class=\"venobox block transition-opacity hover:opacity-90\" style=\"cursor: zoom-in;\">\n                <img decoding=\"async\" src=\"https:\/\/bpi.dk\/wp-content\/uploads\/2026\/09\/Wine-Cooler-Visuals-1.png\" alt=\"\" class=\"inline-block max-w-full max-h-full\" loading=\"lazy\" height=\"1654\" width=\"2339\">\n                    <\/a>\n            <\/div>\n\n    <script>\n        document.addEventListener(\"DOMContentLoaded\", function() {\n\n            const allImages = document.querySelectorAll(\"img\");\n\n            allImages.forEach((img) => {\n                img.removeAttribute('width');\n                img.removeAttribute('height');\n            });\n\n        });\n    <\/script>\n\n            <\/div>\n        <\/div>\n    <\/div>\n<\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_heading\">\n<h5 id=\"h-the-fan-system\" class=\"wp-block-heading\">The fan system<\/h5>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">Fans circulate air through the cabinet or across heat exchangers, and generate airborne sound through blade-air interaction, turbulence around inlets and outlets, and motor or bearing behaviour. The installed environment matters too: restricted airflow, sharp transitions or nearby grilles can increase turbulence and change the acoustic character. Just as important is the fan mounting. Even when airborne fan noise is low, vibration from the motor can transfer through the fan housing, bracket, screws and cabinet structure, exciting the cabinet panels so they radiate sound into the room as structure-borne noise.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_heading\">\n<h5 id=\"h-the-compressor-system\" class=\"wp-block-heading\">The compressor system<\/h5>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">The compressor, usually in the lower mechanical compartment, can generate both airborne and structure-borne noise from mechanical forces, refrigerant pressure pulsations, valve movement and shell vibration. Rubber grommets or other resilient mounts are normally used to isolate it, but a soft material does not automatically guarantee effective isolation; its stiffness, geometry, load and temperature behaviour all affect how much vibration reaches the cabinet. Refrigerant tubing can also create its own transmission path if a tube contacts a panel or bracket directly, bypassing the intended isolation.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_heading\">\n<h5 id=\"h-refrigerant-flow-and-secondary-noises\" class=\"wp-block-heading\">Refrigerant flow and secondary noises<\/h5>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">Depending on the system and operating condition, users may also notice refrigerant flow and pressure pulsations, expansion-device noise, contact between pipes or panels, loose shelves or bottle supports, and short clicks during start-up or shut-down. These sounds are often modest in level but draw attention because they are tonal, irregular or unexpected.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_heading\">\n<h4 id=\"h-airborne-and-structure-borne-noise-need-different-solutions\" class=\"wp-block-heading\">Airborne and structure-borne noise need different solutions<\/h4>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p class=\"wp-block-paragraph\">Airborne noise travels directly from a component through the air, such as aerodynamic fan noise or sound radiated from the compressor shell. Structure-borne noise begins as mechanical vibration that travels through brackets, screws, panels or pipes before another surface radiates it as audible sound. The distinction matters in practice: a material that absorbs airborne sound may do little for a rigid vibration path, and adding mass or absorption around a component will not fix a poorly isolated bracket.

At BPI, this work combines noise and vibration testing, material expertise and prototype validation, supporting both new product development and the optimisation of existing wine-cooler designs. By identifying where vibration transfer actually occurs, isolation concepts can be tailored to the available space, load conditions and required acoustic performance, so that quietness is designed in, not added afterwards.<\/p>\n<\/div><\/div><\/div>\n\n<div class=\"container\"><div class=\"lg:mx-auto max-w-2xl\"><div class=\"core_paragraph\">\n<p
