Acoustic Insights

Practical notes on the acoustic problems that show up in offices, meeting rooms, classrooms, and commercial interiors.

Sustainability

Recycled PET acoustic panels: from plastic bottles to sound panels

SOF PET panels turn recycled bottles into high-NRC acoustic treatment with lower water use, lower energy use, zero VOC emissions, and a practical end-of-life recycling path.

Standards

WELL building standard acoustics: what architects need to know

WELL v2 treats sound as a core building-health requirement, which means acoustic planning has to start early enough to shape partitions, doors, ceilings, and HVAC noise targets.

Infographic showing speech privacy zones in an open office, including full distraction, partial distraction, and background noise zones with absorb, block, and mask strategies

Office Acoustics

Distraction distance: the metric that defines open office acoustics

Distraction distance explains why some open offices leak conversations across the floor and why absorption, barriers, and controlled background sound have to work together.

Infographic comparing acoustic panel coverage needs for hard-surface rooms, mixed-surface rooms, and already dampened rooms with first reflection point guidance

Acoustic Basics

How much acoustic panel coverage does your room actually need?

Panel coverage is not a fixed percentage. Room volume, existing finishes, target RT60, and first reflection points decide how much treatment a space actually needs.

Infographic explaining 38 to 50 dB STC acoustic doors, room types that depend on privacy, and the components that improve door sound isolation

Soundproofing

STC ratings explained: what your acoustic door actually blocks

STC ratings turn door privacy into a measurable specification, but the rating only matters when the core, seals, frame, and installation all work together.

Infographic explaining what 0.95 NRC acoustic ceiling panels do in classrooms, offices, meeting rooms, and training spaces

Acoustic Basics

What 0.95 NRC ceiling panels actually do for your room

High-NRC ceiling panels change a room at the surface that matters most, lowering reverberation, improving speech clarity, and reducing the need for excessive wall treatment.

Acoustic Design

The three axes of acoustic design: absorb, block, isolate

Acoustic treatment, sound blocking, and vibration isolation solve different problems. Strong acoustic design only works when all three axes are considered together.

Infographic comparing an untreated auditorium echo chamber with an acoustically tuned auditorium where every seat has clearer speech and balanced reverberation

Auditoriums

Auditorium acoustics: from echo chamber to every seat crystal clear

Auditorium acoustics are judged from the back row: speech must stay clear, reverberation must stay controlled, and the room still needs enough life for events.

Infographic showing how ceiling reflections spread sound across an entire office floor compared to contained wall reflections, with ceiling treatment options including baffles, clouds, and performance tiles

Office Acoustics

Why ceiling acoustic treatment matters more than wall panels

In most offices, the ceiling spreads speech and background noise farther than the walls, which is why ceiling treatment often delivers the biggest acoustic improvement.

Infographic explaining NRC ratings, showing frequency range limitations, panel thickness impact on absorption, flush mount vs air gap mounting comparison, and material NRC comparison chart from marble to acoustic panels

Acoustic Basics

NRC ratings: what the number actually means (and what it hides)

NRC is a useful shorthand for acoustic absorption, but it leaves out the frequency range, panel thickness, and mounting details that decide how a product performs in a real room.

Infographic comparing treated vs untreated conference rooms for video calls, showing RT60 values, Speech Transmission Index scale, microphone reflection diagram, and recommended treatment placement

Meeting Rooms

Why your video calls sound terrible (it's not your platform, it's your room)

Most bad video-call audio is not the platform or the microphone. It is the conference room sending reflections into the mic.

Office Acoustics

The glass wall trap: beautiful design, terrible acoustics

Glass makes offices look open and modern, but it reflects almost all sound and can turn meeting rooms into loudspeakers for the whole floor.

Infographic showing focused brain vs distracted brain in open offices, conversation bandwidth of 1.6, decibel scale from 40 dB to 70 dB, and acoustic treatment strategies for the 3-6 foot speech zone

Office Acoustics

Open office acoustics: why one conversation costs you 66% of your focus

Open office speech is uniquely distracting because the brain is wired to process language, even when employees are trying not to listen.

Infographic showing RT60 targets for different room types from meeting rooms at 0.4 seconds to concert halls at 2.2 seconds, with Sabine formula, WELL and ANSI standards marked, and speech vs music reverb comparison

Acoustic Basics

Reverberation time (RT60): the number that defines how your room sounds

RT60 measures how long sound lingers in a room, and it explains why a boardroom, classroom, office, and concert hall need very different acoustic targets.
