Está diseñado para disminuir la presión de sonido mediante cámaras y amortiguamiento del sonido mediante fibra de vidrio y materiales que absorben el sonido. También se aprovecha el fenómeno de <a href="/wiki/Resonancia" title="Resonancia">resonancia</a> de la columna de gas de modo que el largo de la columna se escoge para que resuene a frecuencias con defase de 180° de modo que ocurra la cancelación del sonido <a href="/wiki/Interferencia_destructiva" title="Interferencia destructiva">interferencia destructiva</a>. Un fenómeno inevitable es que cualquier dispositivo que restrinja el libre flujo de los gases de escape, influirá en el funcionamiento del motor al limitar la capacidad de salida de los gases y se notará como una menor fuerza de salida en los pistones y menor potencia y trabajo entregado, por lo que el cuidadoso diseño del silenciador será un compromiso entre la potencia y la comodidad que el motor logre. Existen dispositivos que cambian el flujo de gas y sonido de los silenciadores su instalación y modificación de los sistemas de escape está normalmente regulado en los distintos países y lugares de modo que puede estar incluso penado dependiendo de la aplicación y lugar donde se usen los motores modificados. </p><p>En algunos países es común el uso de un dispositivo similar llamado <b>roncador</b> pero a diferencia del silenciador como tal aumenta el nivel de sonido del escape. Generalmente se usa en vehículos de competencia, mas en la mayor parte de los países está prohibido debido a la contaminación sónica que suele generar. </p> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/Archivo:Silencer_001.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/0/01/Silencer_001.JPG/220px-Silencer_001.JPG" decoding="async" width="220" height="146" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/0/01/Silencer_001.JPG/330px-Silencer_001.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/0/01/Silencer_001.JPG/440px-Silencer_001.JPG 2x" data-file-width="1280" data-file-height="850" /></a><figcaption>Un silenciador en un <a href="/wiki/Motor_di%C3%A9sel" title="Motor diésel">motor diésel</a> de gran camión</figcaption></figure> <div class="mw-heading mw-heading2"><h2 id="Referencias">Referencias</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Silenciador_(motores)&action=edit&section=3" title="Editar sección: Referencias"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="listaref" style="list-style-type: decimal;"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><span id="CITAREFASALE2024-05-27" class="citation web">ASALE (27 de mayo de 2024). <a rel="nofollow" class="external text" href="https://www.asale.org/damer/mufla">«mufla | Diccionario de americanismos»</a>. <i>«Diccionario de americanismos»</i><span class="reference-accessdate">.
