Introduction
*This practice examination is designed to assess the comprehensive knowledge and practical decision-making
skills required for professional audio engineering certification. Candidates will demonstrate mastery of
foundational acoustical theory, applied signal flow, microphone deployment, digital audio workstation
proficiency, mixing and processing techniques, loudness standards, system connectivity, and legal-ethical
responsibilities. The exam consists of 200 multiple-choice questions, including real-world scenarios that test
diagnostic reasoning and industry-standard practices. Each item is followed by a verified correct answer and a
,concise rationale. This assessment emphasizes application over memorization, preparing candidates for both
studio and live sound environments. All questions reflect current industry norms and safety regulations.*
SECTION ONE: QUESTIONS 1–100
Question 1
A singer is experiencing excessive sibilance during a vocal tracking session. The microphone is a large-
diaphragm condenser positioned 8 inches from the performer. Which of the following is the most effective
FIRST action to reduce sibilance before applying processing?
A. Engage a de-esser plugin and set the threshold to -20 dB
B. Switch to a dynamic microphone with a presence boost
C. Reposition the microphone slightly off-axis (15–20 degrees)
D. Apply a low-pass filter at 8 kHz on the input channel
🟢C
🔴 RATIONALE: Off-axis positioning reduces direct high-frequency energy from plosive and sibilant sounds.
This addresses the root acoustic issue before electronic processing, preserving natural tone while minimizing
harshness.
Question 2
A loudspeaker specification lists sensitivity as 90 dB SPL (1W/1m). How much amplifier power is required to
produce 102 dB SPL at 1 meter in free space?
,A. 4 watts
B. 8 watts
C. 12 watts
D. 16 watts
🟢D
🔴 RATIONALE: Every +3 dB requires doubling power. From 90 dB to 102 dB is a +12 dB increase, requiring 2^4
= 16 times power. 1W × 16 = 16W.
Question 3
During a live concert, the lead vocal microphone begins feeding back at 2.5 kHz. The engineer uses a graphic
equalizer. Which of the following is the most appropriate gain reduction?
A. Cut 2.5 kHz by 3 dB
B. Cut 2.5 kHz by 12 dB
C. Boost 2.5 kHz by 6 dB
D. Cut 125 Hz by 6 dB
🟢A
🔴 RATIONALE: A subtle cut (3–6 dB) at the exact feedback frequency preserves vocal clarity while eliminating
the ring. Excessive cutting degrades tone. Boosting worsens feedback.
Question 4
What does the term “Nyquist frequency” refer to in digital audio?
, A. The maximum audible frequency for human hearing
B. Half the sample rate, above which aliasing occurs
C. The optimal bit depth for 24-bit recording
D. The frequency of dither noise in 16-bit systems
🟢B
🔴 RATIONALE: The Nyquist frequency equals sample rate ÷ 2. Frequencies above this cause aliasing distortion
unless removed by an anti-aliasing filter.
Question 5
An audio engineer receives a multitrack session with a snare drum track that contains bleed from the hi-hat
(prominent at 8 kHz). Which processing method will most effectively reduce the bleed without muting the
snare?
A. Apply a low-pass filter at 3 kHz
B. Use a multiband expander centered on 8 kHz
C. Insert a gate triggered by the snare’s fundamental
D. Duplicate the track and invert polarity
🟢B
🔴 RATIONALE: A multiband expander selectively reduces gain in the 8 kHz region only when the hi-hat bleed
is present but snare is not hitting, preserving snara attack while attenuating bleed.
Question 6
A client requests a master for streaming at -14 LUFS integrated. The current master measures -9 LUFS
integrated with a True Peak of -1 dBTP. What is the correct first step?
