This acoustic server rack is specifically designed to minimize external acoustic levels caused by network equipment. The SRQ18U is ideal for small offices, recording studios, retail applications, classrooms and other areas where you need equipment to be secure, organized and quiet. Special foam sound-dampening baffles are built into the front and rear doors and side panels to reduce acoustic levels by as much as 28 decibels. Less noise makes for a calmer work environment that encourages productivity.
