Komponen yang terdedah kepada hingar dalam peranti hidraulik biasanya dianggap sebagai pam dan injap, dan injap terutamanya injap limpahan dan injap undur elektromagnet. Terdapat banyak faktor yang menyebabkan bunyi bising. Bunyi injap limpahan mempunyai dua jenis bunyi kadar aliran dan bunyi mekanikal. Bunyi halaju aliran terutamanya disebabkan oleh getaran minyak, peronggaan dan kejutan hidraulik. Bunyi mekanikal terutamanya disebabkan oleh kesan dan geseran bahagian dalam injap.
