| Question | Answer |
| What is the difference between Critical Listening and Analytical Listening? | Critical Listening - Objective Listening to physical details of music - Pitch - Dynamic Range - Timbre - Rhythmic properties Analytical Listening - Subjective -Concerned with meaning, emotion, feeling, subtext associated with music. Varies from listener to listener |
| What is a best listening environment? (4) | 1. Suitable area 2. Low Light 3. Monitor Setup 4. Mental Preparedness |
| What is the best monitoring setup? | 1. Have speakers 1m from your head 2. Ear level height 3. Equilateral triangle between head and speakers (30degrees - L/R from center 4. If you are headphones, buy the best headphones possible |
| How can you mentally prepare before critically listening to Meg? (5) | 1. Well rested 2. Eat before 3. Ensure no pressing appointments 4. Know what you're listening for 5. Review listening process for effectiveness |
| What is the ILM (Intergrative Listening Model) 4 Stages | 1. Prepare to listen 2. Apply listening process 3. Assess listening performance 4. Setup new goals to listen Repeat |
| Explain the human hearing mechanism and the process of auditory transduction | -Sound waves travel through auditory canal -Hits the tempanic membrane -Malleus, Incus, Stapes hit the oval window -Stimulates the cochlea -Pressure is relieved through round window -Organ of corti is stimulated which sends neurons to the brain |
| The Semi-Circular Canal is also known as? | Balance Organ |
| Sound waves can behave in two ways - what are they | Periodic and Transient |
| Explain periodic sound waves | Starts smoothly and repeat over time |
| Explain transient sound waves | Cycles start suddenly and decay quickly |
| Wavelength is the? | Distance between peaks |
| Frequency | Direct relationship to pitch L=L=L H=H=S |
| Amplitude | Strength of the wave Direct relation to LOUDNESS SPL measured in DB |
| Phase | Start of given cycle |
| Simple Wave | Pure Tone |
| Complex Wave | Multiple sine waves Real world musical sounds |
| Noise | All frequencies heard simulataneously |
| What are the types of hearing loss and how are they caused? | Conductive Hearing Loss - Caused by a mechanical problem in the ear canal or middle that blocks the conduction of sound Sensorineural Hearing oss - Damage to inner ear, auditory nerve, or auditory nerve pathways |
| What is the most common form of hearing loss? | Sensorineural hearing loss - caused by prolonged exposure to sound or loud noise. |
| How can you prevent hearing loss? (4 steps) | 1. Restrict 2/3rds of volume 2. Rest 5 mins every 30 mins. 3. Listen when rested, recharged and focused 4. If tired, mouth stretching exercises will help loosen muscles and tendons in middle ear |
| What is meant by pitch? (3) | -Describes a particular frequency being maintained -Pitch represents the perceived fundamental frequency of a sound -Can be measured in Hertz (Hz) E.G A=440 |
| Why A440Hz? (3) | 1. Pitch shared by most instruments 2. Common note in music compositions 3. It's a nice round figure |
| What is the formula for finding a perfect 5 from A | Take A440 half it and then add it to A440. E.G 440/2 = 220 440 + 220 = 660 The Hz value of E A P5 above A is E 660Hz |
| How can we define Rhythm? (3) | 1.Collection of sound events through time 2. Often using transient waveforms 3. A pattern of musical events which lend itself to repetition |
| What is destructive interference? | Cancelling each other out |
| How do you identify odd time signature? (3) | 1. Listen for underlying beat 2. Recognize melodies that repeat 3. Listen to accents in music |
| What is the BPM of the following tempos Largo Larghetto Adagio Andante Moderato Allegro Presto Prestissimo | Largo=40-60 Larghetto=60-66 Adagio=66-76 Andante=76-108 Moderato=108-220 Allegro=120-168 Presto=168-200 Prestissimo=200-208 |
| What is dynamics | Loud and soft |
| What is amplitude? | The lateral distance of wavelength |
| What is sound intensity | The amplitude of the sound emitted by the source |
| What is sound pressure level | The amplitude of the listeners position - (receiving the sound) |
| What is loudness | Amplitude as perceived by the listener- it's subjective |
| How many dB does it take to double the sound? | 10 |
| What is the optical frequency for human hearing | 5000Hz (pipe Organ) |
| What is the Workplace Standard for dB in Australia? | 85dB for 8 hours (90dB USA) |
| What is Timbre? | Tone colour |
| What is a spectral envelope? | A graph which displays the distribution of frequencies over time |
| What is the amplitude envelope? | A graph- attack sustain decay |
