The question in Paper X — Design
Radiation from a vibrating piston
The constraints stated together: piston-like motion, adequate excursion, stiffness against mass, and the directivity that follows from ka.
In plain terms: The free demonstration of what a loudspeaker diaphragm has to do at once — the reason for the cone.
Audio Engineering Society library
The alternatives assessed on record: electrostatic panels, horns, and compression drivers, with the efficiency and bandwidth each trades.
In plain terms: The engineering library where the rival designs and their costs are documented.
The electromechanical model: the moving-coil transducer’s parameters, and where each alternative topology departs from them.
In plain terms: The free Stanford treatment of how a loudspeaker actually works, and why the standard design persists.

36. Is the concert hall an instrument? Distinguish what the room adds from what it merely transmits, and locate the threshold in the measurements.
The question in Paper X — Design
ISO 3382-1:2009 — room acoustic parameters
The threshold in the measurements: reverberation time, early decay, clarity and lateral energy — the room’s contribution made quantitative.
In plain terms: The free record of the standard that says which numbers describe what a hall adds.
Reverberation — demonstrations
The distinction demonstrated: transmission and early reflection against the diffuse tail that constitutes the room’s own voice.
In plain terms: The free demonstration separating what the room passes on from what it adds.
Audio Engineering Society library
The hall literature: measured comparisons of the celebrated rooms, and the parameters that correlate with musicians’ judgements.
In plain terms: The engineering library where the great halls are measured rather than praised.

37. What did the electric guitar make possible that the acoustic did not? Answer from the pickup, the amplifier, and the feedback loop, and say which of the three is the design.
The question in Paper X — Design
The instrument in the museum record
The three components historically separated: the magnetic pickup, the amplifier stage, and the acoustic–electric loop between them.
In plain terms: The free museum record of the instruments themselves, component by component and player by player.
Music acoustics — strings, bodies and pickups
What the pickup changes: transduction of string motion alone, bypassing the body’s filtering and the radiation it imposes.
In plain terms: The free acoustics page explaining what the electric instrument stopped doing that the acoustic one had to do.
Nonlinear elements and distortion
The feedback loop treated as design: nonlinearity and gain converting an artefact of the system into a controllable instrument parameter.
In plain terms: The free Stanford text on distortion and feedback — the mechanism by which a fault became a technique.
Background: Electric guitar · Audio feedback
38. Is the synthesiser a keyboard instrument? Say what the interface inherited from the piano, what it inherited from the patch bay, and what the mismatch costs the player.
The question in Paper X — Design
The Bob Moog Foundation archive
The interface lineage documented instrument by instrument: keyboards, ribbons, patch bays, and sequencers, with what each controlled.
In plain terms: The free archive of the man who put a piano keyboard on a synthesiser — where the inheritance can be traced.
The mismatch made explicit: note-on and velocity as the transmitted parameters, and the continuous control the keyboard cannot express.
In plain terms: The free specification showing exactly which gestures the keyboard interface can and cannot send.
New Interfaces for Musical Expression — proceedings
The alternatives researched: continuous controllers, gestural and tangible instruments, and the evaluation criteria proposed for them.
In plain terms: The free archive of two decades of attempts to design a better musical interface than the keyboard.
Background: Synthesizer · Music controller
39. Are the loudness war and the dynamic-range compression that produced it a design failure or a design response? State the incentive, and say what a measurement standard such as LUFS can and cannot correct.
The question in Paper X — Design
EBU R 128 — loudness normalisation
The corrective specified: programme loudness in LUFS with a target and tolerance, removing the advantage that level competition rewarded.
In plain terms: The free official standard that ended the incentive to make everything louder — in broadcast, at least.
ITU-R BS.1770 — loudness and true-peak measurement
The measurement defined: K-weighting and gating, the algorithm on which every loudness target now depends.
In plain terms: The free official recommendation defining how loudness is measured at all.
Audio Engineering Society library
The evidence on the trade: measured dynamic-range compression across decades, and listener preference studies that complicate the failure verdict.
In plain terms: The engineering library where the loudness war is documented with measurements rather than complaint.
Background: Loudness war · LUFS
40. Is the streaming interface an instrument of listening? Say what the playlist, the skip, and the recommendation change about the object listened to, and whether the change is in the artefact or in the audience.
The question in Paper X — Design
New Interfaces for Musical Expression — proceedings
The listening interface as designed object: skip, queue, and recommendation treated as instrument parameters with measurable effects on use.
In plain terms: The free research archive that takes the controls of listening as seriously as the controls of playing.
Publications of a streaming platform’s research group
The mechanism documented from inside: sequential recommendation, skip modelling, and the feedback between exposure and preference.
In plain terms: The free research archive of the people who build the interface — what the skip and the playlist actually do.
Simplicity is highly overrated
The evaluative caution: preference measured in use rather than asserted from the interface’s form, and the gap between the two.
In plain terms: The free essay warning against reading a design’s effects off its appearance — the discipline this question needs.
