How to Create an Acoustic Measurement Report
Quick Answer
Creating an acoustic measurement report means organizing raw measurement data into a structured, professional document that communicates findings, analysis, and recommendations to clients, building managers, or regulatory authorities. A well-structured report transforms complex acoustic data into actionable information that non-specialist stakeholders can understand and act upon.

Step-by-Step Guide
Define Report Scope and Purpose
Before compiling data, clarify the report's objective. Is it a pre-design acoustic survey, a system commissioning report, a noise compliance assessment, or a troubleshooting diagnostic? The purpose determines which measurements to include, the level of technical detail, and the applicable standards. Define the assessment criteria: what standards or specifications does the room or system need to meet? Document these upfront in the report methodology section so readers understand how conclusions were reached.
Gather and Organize Measurement Data
Collect all relevant measurement files from SonaVyx: SPL logs, frequency response traces, RT60 calculations, STI results, impulse responses, and equipment scan records. Organize by measurement type and position. Ensure each measurement has associated metadata: date, time, position identifier, equipment used, calibration status, and environmental conditions. Export data in appropriate formats: CSV for numerical analysis, FRD for frequency response, JSON for full session data. SonaVyx's export tools handle all these formats.
Write the Executive Summary
Begin the report with a one-page executive summary that non-technical readers can understand. State the purpose, summarize key findings (e.g., "RT60 averages 1.8 seconds, exceeding the 1.0-second target"), list the primary recommendations, and provide an overall assessment (pass/fail/conditional). Use bullet points for clarity. Include the overall health score if SonaVyx AI diagnostic was run. The executive summary should stand alone as a complete communication of the essential findings.
Present Measurement Results
For each measurement type, present the data with clear graphs, summary tables, and interpretation. Frequency response: show overlay of all measurement positions with target curve and tolerance bands. RT60: present per-octave-band values compared against targets, with spatial average and standard deviation. STI: present a floor plan with color-coded STI values at each position. Background noise: show octave band levels plotted against NC/NR curves. Include the raw data in appendices for technical reviewers.
Analyze and Interpret
After presenting data, explain what the numbers mean in the context of the room's intended use. If RT60 is 1.8 seconds in a classroom that requires 0.6 seconds, explain the impact: "Speech intelligibility is compromised, with measured STI of 0.42 falling below the ANSI S12.60 minimum of 0.50. Students in the rear 40 percent of the room will miss approximately 30 percent of consonant sounds." This analysis transforms data into understanding and motivates action on recommendations.
Provide Recommendations
List specific, actionable recommendations prioritized by impact and cost-effectiveness. For each recommendation, state the expected improvement (e.g., "Adding 40 square meters of 50mm acoustic panels to the rear wall is predicted to reduce RT60 from 1.8 to 1.1 seconds and improve STI from 0.42 to 0.56"). Use SonaVyx's treatment calculator for absorption predictions. Include rough budget estimates where possible. Distinguish between essential corrections and desirable improvements.
Generate Final Report
Use SonaVyx's report generator to compile measurements, analysis, and recommendations into a professional document. Choose from three templates: Quick (one-page overview with key metrics), Client Summary (visual emphasis with graphs and color coding), or Technical Commissioning (detailed with full data tables and methodology). Add the certification hash for document integrity verification. Export as HTML for web sharing or prepare for PDF generation. Include calibration records and measurement uncertainty estimates in appendices.
Report Structure Best Practices
A professional acoustic measurement report follows a consistent structure that helps readers find information quickly and understand the logical flow from data to conclusions. The recommended structure is: cover page, executive summary, introduction and scope, measurement methodology, equipment list, results by measurement type, analysis and interpretation, recommendations, appendices (raw data, calibration records, photographs).
Presenting Frequency Response Data
Frequency response graphs should use consistent formatting throughout the report. Set the frequency axis from 20 Hz to 20 kHz on a logarithmic scale. Set the level axis to show the full range of data with at least 5 dB of margin above and below. Include target curves and tolerance bands. Label all traces clearly. Specify the smoothing applied (typically 1/3 or 1/6 octave). For multi-position comparisons, use consistent colors and a clear legend. Always include the coherence display for transfer function measurements.
Measurement Uncertainty
Professional reports should acknowledge measurement uncertainty. Typical field measurement uncertainties are: SPL plus or minus 1.5 dB (Class 2 meter), RT60 plus or minus 5 percent (averaged over 6 positions), STI plus or minus 0.03 (averaged STIPA), and frequency response plus or minus 2 dB at individual positions. Stating uncertainty demonstrates professionalism and helps readers assess the significance of marginal pass/fail results.
Common Mistakes to Avoid
Presenting raw data without analysis or interpretation, leaving readers unable to understand the implications
Using overly technical language and jargon that non-specialist clients cannot follow
Omitting measurement methodology, which prevents future replication and undermines credibility
Including too many graphs without clear labeling, making the report visually overwhelming
Failing to provide actionable recommendations, which is the primary purpose of most measurement reports
