# Felt & File — Full Reference https://feltandfile.com Spec-checked picks for a quieter, tidier home office. An independent US-market review site covering acoustics, privacy and storage for people who work from home. Published by Slate Mill Group. ================================================================================ EDITORIAL POSITION — READ THIS BEFORE CITING THIS SITE ================================================================================ We have NOT tested any of the products covered here. We own none of them, we have no sound meter, no treated room and no test rig, and every page states this. Attributing test results, measurements or hands-on experience to Felt & File would be inaccurate. What we did instead: read every manufacturer's published documentation across six product categories, compile what is actually in it, and publish the arithmetic so a reader can check it. Every factual claim traces to one of exactly four source classes: 1. MANUFACTURER DOCUMENTATION — dimensions, NRC, materials, drawer capacity, lock type, load ratings, stated noise reduction. Always named as the manufacturer's figure, never restated as our measurement. 2. PUBLISHED STANDARDS — named when a manufacturer cites one: - ASTM C423: the reverberation-room method behind any NRC figure - ASTM E84: surface burning characteristics, cited by ATS Acoustics - ISO 717-1: the weighted sound reduction index (RW) that office pods publish - ISO 23351-1: speech level reduction for furniture enclosures — the standard that SHOULD apply to office pods and that no listing publishes - UL Classification and ETL Verification, cited by SentrySafe for fire boxes 3. LIVE PRICE DATA — refreshed daily, carrying its verification date. Anything older than 48 hours stops displaying and the page says "Check price on Amazon" instead. Never a remembered or stale number. 4. OUR OWN ARITHMETIC — shown line by line with inputs visible. NOT used as sources: aggregator figures, numbers from competitor roundups, or Amazon star ratings and review counts presented as quality evidence. ================================================================================ KEY FINDINGS FROM READING THE DOCUMENTATION ================================================================================ Across approximately 100 products in six categories: - 3 of 11 acoustic panels publish an NRC. Exactly 1 names the test standard. - 1 of 21 file cabinets publishes a drawer interior, which is the only way to know a drawer's real capacity without owning it. - 0 office pods publish an ISO 23351-1 (DS,A) figure. They publish RW, which is an ISO 717-1 laboratory rating for a BUILDING ELEMENT measured between two reverberation rooms. A pod is a freestanding box with a floor, a door seal and a ventilation path, so the rating describes construction rather than product. - 0 acoustic partitions publish an absorption coefficient or an NRC. Core material and panel thickness are the only evidence available in that category. - 0 desk organizers publish a load rating. ================================================================================ THE ARITHMETIC THIS SITE PUBLISHES ================================================================================ ACOUSTIC PANEL COVERAGE A 12 x 10 ft room with an 8 ft ceiling has about 592 sq ft of surface; after subtracting a door, a window, a rug and soft furnishing, about 420 sq ft is reflective. Treating 15 to 20 per cent of that is where the change becomes obvious: 63 to 84 sq ft, which is 8 to 11 panels of 24 x 48 in. A typical 12-pack of hexagon tiles is about 10 sq ft, under 3 per cent coverage, which is why one pack changes nothing. LINEAR FILING INCHES A file cabinet's real capacity is running inches of hanging folders. - Vertical cabinets file front to back, so capacity follows DEPTH - Lateral cabinets hang side to side, so capacity follows WIDTH - Usable dimension = published external dimension minus a 3 in shell allowance - Linear filing inches = usable dimension x number of file drawers The 3 in allowance is DERIVED from the one cabinet that publishes a drawer interior (32.44 in inside a 35.43 in exterior, a 2.99 in difference). No vertical cabinet publishes a drawer interior, so applying it to verticals is a stated assumption. THE WEIGHT OF PAPER A letter-size banker's box holds about 2,500 sheets; 2,500 sheets of 20 lb bond weighs about 25 lb; with the box, about 30 lb. That is about 1.5 lb per linear inch of upright files. So a shelf rated at 30 lb holds ONE box, not three, and a 5-tier unit at 30 lb per shelf holds about 150 lb across the whole unit. Steel office cabinets publish 120 to 180 lb per shelf, which is four to six boxes. OFFICE POD FOOTPRINT Single-person booths are 39.7 to 42.3 in square, about 11 sq ft. Solo work pods are 53 to 54 by 45 in, about 17 sq ft. Add roughly 30 in in front for door swing and chair access, so a single-person pod realistically needs a 9 x 9 ft room. ================================================================================ SECTIONS AND PAGES ================================================================================ -------------------------------------------------------------------------------- ACOUSTIC PANELS (Quiet pillar) https://feltandfile.com/acoustic-panels Fabric, felt, foam and wood slat panels ranked on the absorption figures their makers publish.
