질문이 있으십니까? 채팅하기

고객 질문 및 답변

  • 의문: What can this tool help me with?

    답변: This tool can help you answer questions about your audio system's performance.
  • 의문: How precise are the audio signals on the CD?

    답변: The audio signals on the CD are mathematically perfect within the limitations of the CD audio format.
  • 의문: What instruments are needed for precise measurements?

    답변: Inexpensive sound pressure level meter, voltmeter, and optionally precision microphone, oscilloscope, or spectrum analyzer.
  • 의문: Are the tracks/frequencies recorded at 0dB?

    답변: Only the Saturated Distortion Suite, tracks 97 and 99, are recorded at 0 dB. All others are recorded at -6 dB.
  • 의문: Does this have a 1000 Hz sine wave tone? If so, how long does it play?

    답변: There is a 10 second 1000 Hz sine wave in track 4, a single track including 13 announced sinusoids at octave intervals within decade intervals. There is also a separate 10 second 1016 Hz sinusoid track that can be repeated indefinitely on many players.
  • 의문: Will this play continuous 80 Hz tones?

    답변: Most CD players can continuously repeat a selected track. If you set the 80 Hz track to repeat, there will probably be a short silence between repetitions.
  • 의문: Will this let you know if each speaker (woofer, midrange, tweeter, super tweeter) is working or if the crossover or drivers are bad?

    답변: Yes, that should be easy to determine. Play sinusoids of about 100 Hz, 1000 Hz, 4000 Hz, and 10000 Hz to exercise the woofer, midrange, tweeter, and super tweeter, respectively. With a stereo setup, each tone should appear to come from midway between the speakers if the speakers are responding identically at each frequency. For additional precision, you can use a sound recording program on your PC or a sound level meter to measure relative levels.

Contemporary Communications Clinical Diagnostic Test Kits ‎PTS-CD Editorial Review

** Precision Test Signals** Precision Test Signals has garnered a niche following among audio enthusiasts and professionals looking for a reliable means to evaluate their sound systems. Customers have found the frequency response sounds particularly useful, with many highlighting their ability to gain insights into their own hearing capabilities—a helpful feature for those concerned about potential hearing loss. The range of frequencies offered has been appreciated, with tracks capable of reaching as low as 5 Hz, which some users excitedly mention can produce a significant impact on sound systems. Despite its strengths, the disc lacks a comprehensive stereo setup guide and some users have suggested that a dedicated pink noise track would further enhance its utility. Those using the disc for balance checks have praised the pink noise but expressed a desire for more tracks focused purely on individual channels rather than a combined sound. A further common complaint is the absence of a printed track listing, which leaves some customers taking the initiative to create their own for convenience. Overall, Precision Test Signals proves to be a valuable tool for audio calibration and personal hearing assessment, fulfilling a specific need in the market while also inviting suggestions for improvement. **
