How to Soundproof a Closet for Recording

The door is usually the weakest soundproofing point in a closet recording booth. Most interior doors allow sound to leak through the edges and underneath. To start, if your door is hollow, replace it with a solid-core door. After that, sealing the door properly is critical because even tiny gaps dramatically reduce overall soundproofing performance.

To close those airgaps and stop sound leakage, install the Sound Lock Door Seal Kit. The jamb seals compress when the door shuts and the bottom seal closes the bottom door airgap, preventing noise from entering or escaping. Follow the steps to soundproof your door carefully for best results.

Closet walls are typically thin drywall with very little sound isolation. If outside noise is an issue, upgrading the walls helps prevent sound transmission. You can pick the best approach for you by reading about how soundproofing a wall works. Key improvements include adding mass or using isolation clips, and making sure to seal the perimeter with acoustical wall sealant.

These upgrades help the walls perform better when measured by their STC rating, which describes how well a structure blocks sound transmission.

Once sound leakage is controlled, the next step is improving the acoustics inside the closet. Closets can easily become overly reflective because sound waves bounce between close walls. Adding absorption reduces echoes and produces clearer recordings.

Clothing already hanging in the closet acts as natural absorption. If your closet is still full of clothes, you may only need minimal treatment.

If the closet is mostly empty, consider installing acoustic panels. We have options that range from PolyZorbe and fabric wrapped panels for a high end aesthetic to budget friendly options like CelluZorbe acoustic panels and EcoVerb panels.

These materials absorb sound energy instead of reflecting it, improving clarity during recording. You can also explore a huge variety of acoustical panels designed for studio environments.

Browse our high end foam products. Second Skin acoustic foam comes in shapes like linear wedges, pyramids, and super wedges help break up reflections and control reverberation. Low frequencies can sometimes build up in small rooms, so corner treatment like corner bass traps may also help manage low frequency energy.

Most closet recording booths perform well after door sealing and adding acoustic treatment. However, if noise problems remain, a few additional upgrades may help.

If your closet has a window, you may need to address it because glass easily transmits sound. In that case, the window should be soundproofed using solutions such as custom soundproof window inserts.

Noise may also travel through the ceiling or floor depending on the building structure. Learning how a professional studio handles soundproofing can help guide further upgrades.
