DETAILS
The MDL 4260 S is a single-wall WhisperRoom® booth engineered to provide consistent noise reduction in an efficient 3.5 ft × 5 ft interior footprint. Its expanded length offers more working area than compact formats while still fitting comfortably into residential, commercial, educational, and production environments. The modular construction, durable materials, and reliable acoustic performance make it a versatile solution wherever controlled sound is essential.
WhisperRoom booths have been installed in thousands of professional, residential, and institutional settings for more than three decades, delivering long-term reliability and repeatable acoustic results across many industries.
