      System Performance Calculations

      System Performance Calculations

      by John Siau March 02, 2023 13 min read

      Calculators

      If an audio system is composed of multiple components, we may have detailed specifications for each component, but we will not know the performance of the combined system without doing some calculations. You may have questions such as these:

      • Will my audio system produce audible noise?
      • Will my audio system produce audible distortion?
      • How will my audio components work together as a system?
      • How loud will my audio system play?

      Use Benchmark's online audio calculators to find answers!

      For example, if we know the output power of an amplifier, as well as the sensitivity and impedance of our loudspeakers, we can calculate the maximum sound pressure level that our system can produce.

      PEAK SPL CALCULATOR
      Speaker Sensitivity: dB SPL (2.83 V, 1 M)
      Amplifier Power Per Channel into 8 Ohms: Watts
      RESULTS
      Peak Output Level (at typical listening position): dB SPL

       

      This application note provides interactive examples that help to answer the questions listed above.

      SECRETS Q&A WITH JOHN SIAU OF BENCHMARK MEDIA SYSTEMS

      SECRETS Q&A WITH JOHN SIAU OF BENCHMARK MEDIA SYSTEMS

      by Benchmark Media Systems January 07, 2022 1 min read

      Company History Inter-Sample Overs Listening Tests Power Amplifier Power Supply Test & Measurement ~ HomeTheaterHiFi.com

      Secrets contributor Sumit Chawla recently caught up with Benchmark’s VP and Chief Designer, John Siau to get a little more in-depth on several subjects.

      John Siau, VP Engineering, Benchmark Media Systems, Inc.

      Q: "Benchmark is one of the few companies that publishes an extensive set of measurements, but you also balance that with subjective testing. Can you talk about the equipment, the listening room, and the process for subjective testing?"

      Q: "Was there ever a time where you learned something from a subjective test that was not captured by measurements?"

      Q: "You conducted some listening tests to determine whether distortion in the “First Watt” was audible. What test material did you use for this, and what did you find?"

      Q: "The AHB2 amplifier incorporates THX Audio Achromatic Amplifier technology. When and how did the partnership with THX come about?"

      Q: "Linear power supplies have been and remain quite popular in high-end devices. You favor switch-mode power supplies. When and why did you make this switch?"

      ... and more!
