2. Room Dimensions & Geometry

Accurate dimensional data is critical for volume calculation and RT60 analysis. Measure to the nearest inch or centimeter. For irregular rooms, provide approximate dimensions and describe complexities in the notes.

Room Shape




Does the ceiling height vary throughout the room?


Are there permanent obstructions (columns, beams, soffits, bulkheads)?


Total Floor Area (sq ft)

3. Surface Materials Analysis

Document all major surfaces in the room. The absorption coefficient (α) represents the fraction of sound energy absorbed at 500Hz. Typical values: Concrete 0.02, Glass 0.10, Gypsum Board 0.10, Carpet 0.30, Heavy Curtains 0.50. For accurate results, specify each wall section separately if materials differ.

Do you require frequency-specific absorption analysis (125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz)?


Are there movable elements (curtains, rugs, furniture) that affect absorption?


4. Current Acoustic Performance Assessment

Does the room currently have any acoustic treatment?


What are the primary acoustic problems? (Select all that apply)

Which frequency ranges are most problematic?

Have you measured the current RT60 with professional equipment?


Rate the current acoustic comfort for intended use (1 = Unusable, 5 = Excellent)

5. Target Acoustic Goals & Preferences

Desired acoustic character




Target RT60 at 500Hz (seconds)

Is there a specific critical listening position (e.g., mixing desk, main seating)?


Are there aesthetic constraints (heritage building, designer finishes, minimal visual impact)?


Preferred panel visibility

I understand that absorption coefficients vary with frequency and this analysis uses 500Hz as a reference point

6. Acoustic Calculations & RT60 Analysis

Based on your room dimensions and surface materials, calculate your room's total absorption and RT60. The RT60 formula is: RT60 = 0.049 × (Volume ÷ Total Absorption). A target RT60 of 0.6 seconds or less is recommended for speech clarity and critical listening environments.

Calculated RT60 (seconds)

Is your calculated RT60 greater than 0.6 seconds?


7. Personalized Treatment Recommendations

Use this table to plan acoustic panel placement. Each 2" fiberglass panel (24"×48") provides approximately 4.5 sabins of absorption at 500Hz. Adjust quantities to reach your target RT60. The formula shows total absorption added and estimated cost.

Form Template Insights

Please remove this form template insights section before publishing.


To design an effective acoustic treatment assessment, you need to capture the physical geometry of the space and the sonic "character" of its boundaries. A general template should focus on the relationship between the empty shell and the materials added to it.

Here is a conceptual breakdown of what should be included in such a form to provide a professional-grade analysis:

1. Spatial Dimensions and Geometry

This section defines the physical boundaries of the room. Beyond the basic length, width, and height, consider adding:

  • Room Shape: Identifying if a room is rectangular or non-parallel (angled walls) helps predict "standing waves" or "flutter echoes."
  • Cubic Capacity: A general overview of the total air volume, which dictates how much energy is required to fill the space.

2. Surface Composition Audit

A table for surface materials helps categorize how every square inch of the room responds to sound.

  • Material Classification: Categorize surfaces into Reflective (glass, concrete, hardwood), Absorptive (carpets, heavy drapes), or Diffusive (bookshelves, textured stone).
  • Coverage Mapping: Documenting exactly how much of each material is present on the walls, floor, and ceiling.

3. Acoustic Performance Metrics

This part of the form translates the physical data into a temporal measurement—essentially, how long a sound "hangs" in the air before decaying.

  • Temporal Decay Analysis: A high-level view of whether the room is "live" (echoey) or "dead" (muted).
  • Target Benchmarking: Comparing the current state of the room against industry standards for its intended use (e.g., a home cinema requires a shorter decay than a live tracking room for drums).

Expanded Insights: What Else to Include

To make the form truly comprehensive, you should look beyond just the surface area and volume:

  • Primary Room Use: A voice-over booth needs a much lower reverb time than a listening room for orchestral music. Including a "Usage Type" field allows for customized targets.
  • Frequency Specificity: Materials absorb high frequencies (shimmer) differently than low frequencies (thump). Adding fields for Low, Mid, and High-frequency absorption provides a much more accurate picture of the room’s balance.
  • The "Cloud" and "Corners": Specific fields for ceiling clouds and corner bass traps are vital. Corners are where low-frequency energy accumulates; tracking treatment specifically for these areas is crucial for a balanced sound.
  • Existing Furniture: Large sofas, beds, or heavy bookshelves act as functional acoustic treatment. A section for "Large Objects" helps account for "free" absorption already present in the room.
  • Background Noise Floor: A field to note external noise (HVAC systems, street traffic) helps determine if the room needs Isolation (stopping sound from entering) in addition to Treatment (managing sound within).
