Test Environments that Reveal True Potential
Discover audio excellence in our state-of-the-art lab’s anechoic chamber and listening rooms. Aurio Lab offers high-quality measurements, following industry standards, and is adaptable to non-standard, innovative evaluations supporting research and innovation.
Loudspeaker Anechoic Evaluations
Aurio Acoustics 7m x 5m x 2.7m (24ft x 16ft x 9ft) 80Hz Anechoic Chamber is available for Loudspeaker Measurements for Benchmarking or Product Planning, Product or Concept Development, or Publication. Our low (<6.5dBA, <33dBC) noise floor allows accurate measurement of micro speakers, HOHD, buzz & rattle, or air leaks, or acoustic self noise.
| Loudspeaker Evaluation | Detail | Price* |
|---|---|---|
| System On-Axis SPL Response & Impedance | System 2.83Vrms, 1m Response, & Impedance (CTA-2034) | $1000 |
| System Directivity Responses | On-axis, Listening Window, Early Reflections & Total Power from horizontal & vertical radiation measurement (CTA-2034) | $1500 |
| System Max SPL & Max Input Voltage | Evaluate Maximum Usable Continuous Output SPL, Max Input Voltage and Recommended Amplifier Power (CTA-2034) | $1500 |
| 2-Way Speaker Driver On-Axis Responses & Impedance | Woofer & Tweeter SPL and Impedance (in enclosure, for crossover design) | $1200 |
| 3-way Speaker Driver On-Axis Response & Impedance | Woofer, Mid & Tweeter SPL and Impedance (in enclosure, for crossover design) | $1500 |
| Speaker or System ½ Space Response & Impedance | On-axis, 30-degree off-axis, 60-degree off-axis response (IEC Baffle) | $1000 |
- *Pricing (above) based rectangular bookshelf and floor standing loudspeakers, or drivers easily mounted in IEC baffle. We love a challenge: contact us for pricing for larger or irregular speakers that need custom fixtures, cradles, baffles or brackets
- Services are not limited to “menu” items (above) – it’s impossible to concisely list and price all available services (see below for more). Contact us with your needs.
- Prices improve when combining services – setup/teardown time is spread across evaluations
TV & Sound-bar In-Room Evaluations
TVs, Sound-bars, Smart-Speakers and other audio products designed to be part of our environment have complex acoustics – highly influenced by their placement or setting. In-room evaluations take into account “adjacent boundaries” (table, wall) as well as the unique combination of Direct Sound, Early Reflections and Total Radiation from these products. In-Room (in-situ) evaluations are key in making Critical Evaluation and Tuning choices key in delivering best in class consumer audio products. Aurio Acoustics methods align with rtings.com and best-practices for repeatable and reproducible in-room evaluations.
| In-Room Evaluation Type | Stereo Input: Response, Bandwidth, Variation | Stereo Input: Dynamic Range | Multi-Channel Input: Response Comparison | Multi-Channel Input: Routing Assessment | Price |
|---|---|---|---|---|---|
| Basic (2.x) | Up to 4 Modes | 1 Mode | NA | NA | $2000 |
| Basic (up to 5.1.4) | Up to 4 Modes | 1 Modes | Up to 2 Modes | Up to 2 Modes | $3000 |
| Complete (up to 5.1.4) | All Modes & Tone Settings | Up to 4 Modes | Up to 4 Modes | Up to 4 Modes | $6000 |
Other & Custom Evaluations
Aurio Acoustics consulting and R&D continuously adapts and innovates in Automotive Audio, Micro-Speakers and Wearables, TVs & Sound-bars, Hi-Fi, Professional audio, Microphone Arrays, and evaluation and Testing methodology and tools. This means our lab is always and innovating and adapting to test and evaluate at different scales and areas of focus.
Aurio Acoustics welcomes and specializes in new and innovative. Our low (<6.5dBA, <33dBC) noise floor allows accurate measurement of micro speakers, HOHD, buzz & rattle, or air leaks, or acoustic self noise. If your evaluation doesn’t fit the mold of routine and standard, is iterative, or requires development then it may be a better fit for Aurio Acoustics Consulting.
Other Evaluations
- Loudspeaker system and component benchmarking
- Automotive Audio vehicle and speaker benchmarking
- Micro-speaker and wearable device evaluation
- Microphone evaluation and calibration (free-field response, diffuse-field response, noise-floor, dynamic range, correction curves)
- Outdoor, ground-plane measurements (i.e. subwoofer or large speaker) – weather permitting
- Speaker grille, trim, or packaging impact (coloration, directivity, losses)
- Subjective or listening evaluation
- Root cause analysis – iterative measurement and analysis to reveal the root cause and potential solutions of sound quality or acoustic issues
- Audio System voltage, current, power logging – assessments of first limiting factors in system performance, fidelity, or efficiency
- Operational life, reliability testing
Lab rates and workflow
- Lab rate (including engineer): $250/hour for routine testing, with 4 hour minimum
- Lab rates, testing rates do not include shipping
- Some products/evaluations may have additional fees:
- Large (over 48″, 1.2m) or heavy (over 100lb or 45kg)
- Products requiring fabrication of custom mounts or supports
- Products requiring unusual time to unpack and pack
- We can accept freight deliveries requiring a loading dock – though there is limited room for a forklift inside near the loading dock (load and unload with pallet jack)
- Lab location is in Hollister, in Southern Missouri
