【Deadening & Materials ESDB-24｜Diffusion Sheet for Smoothing In-Car Sound】

If you feel that the sound from the speakers becomes “stuffy” inside the door, or that vocals and fine details are a little harder to pick out, it’s important to revisit the door’s acoustic environment—not just swap out the speakers.

ESDB-24 is a diffusion sheet made specifically for adjusting the sound quality of in-car audio. While coping with the harsh conditions inside the vehicle’s doors, it helps to improve the door’s acoustics through three actions of sound: diffusion, reflection, and absorption.

In particular, it’s a material that’s worth considering if you want to enhance music information around 1kHz to 2kHz, which is said to be easier for the human ear to perceive—so you can bring out clearer vocals and finer instrument detail. It’s designed not simply to make the sound louder, but to help you listen to your usual music in a more organized, refined way.

However, the final result with deadening materials and acoustic tuning materials will vary depending on where they’re applied and the coverage area. It’s important to use them in the necessary places while also considering compatibility with the speaker type, the door structure, and any contents that have already been installed.

At LOGON, we don’t aim only to attach products—we first check the vehicle condition and how the customer listens, then work together to decide where to make changes so that the effect is more likely to be felt. If you’d like to further refine the cohesion and listenability of the sound in combination with speaker replacement and deadening, please feel free to consult us.
