A platformer jump sound has a narrow job, and it is usually discussed in terms of character: bouncy, weighty, retro, cute. That framing assumes a listener whose hearing is roughly typical. For players with hearing loss or auditory sensitivity, the same sound raises two different problems, and the fixes for one can make the other worse.
Hearing loss and auditory sensitivity are not the same condition, and they do not pull the design in the same direction. A player with high-frequency hearing loss needs the jump’s identity to sit in a band they can still hear. A player with hyperacusis or misophonia needs the jump’s sharpest transients softened and its repetition reduced. A sound that is moved up in frequency to survive hearing loss may become harsher for the sensitive listener; a sound that is softened for the sensitive listener may disappear for the player with hearing loss.
The resolution is not a compromise setting in the middle. It is a layered system in which the jump is built from parts that can be independently adjusted, plus a visual channel that carries the information when the audio cannot. The sections below work through the conflict, the layers that resolve it, and the configuration switches that let the player choose which layers they receive.
The Conflict: High-Frequency Hearing Loss and High-Frequency Sensitivity Point in Opposite Directions
Hearing loss is not evenly distributed across the spectrum. High frequencies are typically lost first, and low frequencies last . A jump sound that places its identity in the top octave — a bright square wave, a high shimmer, a sharp click above 6 kHz — is a sound that a significant portion of players will not receive, not because it is too quiet, but because the band is no longer available to them.
Auditory sensitivity runs in the other direction. Hyperacusis involves a heightened sensitivity to sound that can make ordinary sounds uncomfortable or painful, while misophonia involves strong negative emotional responses to specific trigger sounds . The frequencies that are most often difficult are in the 2,000–5,000 Hz range, partly because the ear is most sensitive there and partly because the brain responds differently to high-pitched sounds in that region . A jump that is built around a sharp 3 kHz transient is a jump that a sensitive listener may experience as a stab rather than as feedback.
The two constraints overlap in the same band. The region where a hearing-impaired player may still have usable hearing is roughly the region where a sensitive player is most vulnerable. That is why “move it to the midrange” is not a complete answer: the midrange is exactly where the conflict lives.
Split the Jump Into Layers That Can Be Adjusted Independently
The documented structure of a platformer jump already separates the sound into an impulsion and a motion. The impulsion is short — 75–100 ms — with the pitch only slightly rising. The motion is at least one second long, with the pitch rising one octave . That split is useful for accessibility because the two layers carry different information and have different sensitivity profiles.
The impulsion carries the confirmation: the moment of departure. It needs to be fast, but it does not need to be high. Moving the impulsion’s identity down into the 500 Hz–2 kHz range, with a soft attack rather than an instantaneous click, keeps it audible for a player with high-frequency loss while reducing the sharpness that a sensitive listener reacts to. The transient is still present, but it is a rounded transient rather than a spike.
The motion carries the travel. It can sit higher, because it is longer and the ear has more time to integrate it. A motion layer that rises into the 2–4 kHz region over several hundred milliseconds is less likely to trigger a startle response than a 5 ms click at the same frequency, because the energy is spread over time. The sensitivity problem is not the frequency alone; it is the combination of high frequency and instantaneous onset.
The synthesis guide covers the oscillator and sweep parameters; the accessibility addition is that the two layers should be authored as separate assets with separate filter settings, not as a single file with a fixed spectral shape.
Build the Identity in the Midrange, Not in the Air Band
A jump that identifies itself through a high-frequency shimmer is a jump that loses its identity for a player with high- frequency loss. The fix is not to remove the shimmer; it is to make sure the shimmer is not the only thing carrying the event.
The midrange is where speech intelligibility lives, and it is the region that survives most age-related and noise-induced hearing loss longer than the top octave. A jump whose fundamental and first harmonics sit in the 500 Hz–2 kHz range will remain recognisable as a jump even when the upper harmonics are reduced. The high shimmer can still be present for players who can hear it, but it is a decoration on top of an identity that is already complete without it.
The frequency range guide covers the band placement for cutting through music; the accessibility version is that the identity band should be chosen for the listener first and the mix second. A jump that is audible in a dense mix but inaudible to a player with hearing loss has solved the wrong problem.
Soften the Transient Without Removing It
The transient is the part of the jump that a sensitive listener is most likely to react to. A 1–2 ms click at high amplitude is a startle stimulus; a 10–20 ms attack with a steep but not instantaneous slope is still perceived as immediate, but it does not have the same sharpness.
The safe-listening guidance for game audio recommends look-ahead limiters that compress sudden transients to stay within safe decibel-millisecond ratios, specifically to prevent the acoustic startle reflex . A jump sound does not need a limiter on every playback, but it can be authored with a transient that is already inside that ratio: a slightly longer attack, a slightly lower peak, and a decay that does not snap to silence.
The attack-time guide covers the perceptual thresholds for onset; the accessibility case is that the threshold for “immediate” is wider than the threshold for “startling.” A 10–20 ms attack sits between them.
Variation Is an Accessibility Feature, Not Only an Anti-Fatigue Feature
Repetitive sounds are a documented trigger for misophonia and hyperacusis . A jump that is identical on every trigger is not only fatiguing over time; for a sensitive listener, it is a repeated aversive stimulus. The variation system that exists to prevent repetition fatigue is doing double duty as an accessibility mechanism.
The variation does not need to be wide. The identity threshold for a jump is tight, and a range of ±1 to ±2 semitones is enough to break exact repetition without making the jump read as a different move. A shuffle selection with an exclusion of the last one or two samples prevents the same trigger from recurring immediately, which is the pattern a sensitive listener is most likely to lock onto.
The sound variation system guide covers the pool and selection architecture; the jump variation guide covers the specific ranges for a high-frequency jump. The accessibility addition is that the variation should be treated as a requirement, not a polish step, when the game is intended for a broad audience.
The Visual Channel Is the Only Way to Satisfy Both Constraints at Once
The layered audio solution reduces the conflict but does not eliminate it. There will always be a listener for whom the midrange identity is not enough, or for whom any audible jump at the required repetition rate is aversive. The visual channel is the part of the system that does not depend on the audio compromise at all.
The strongest formulation of the requirement comes from a game-audio course that treats sound as confirmation rather than as an information channel. The rule is that no information is communicated only through sound, and a deaf player or a player with sound off must be able to reconstruct takeoff, landing, and every measurement from the visuals alone . That is a stricter standard than “add a visual indicator for the jump,” because it requires the visual system to carry the timing and the outcome, not just a redundant flash.
In practice, this means the character’s pose and trajectory have to be readable without the jump sound, and any state that the sound would confirm — the exact frame of departure, the height reached, the landing surface — has to be visible in the animation or the environment. A jump sound that is the only confirmation of departure is a jump sound that fails the player who cannot hear it.
The muted-player guide covers the broader principle of designing for players who cannot or will not use audio; the jump-specific case is that the visual confirmation has to be present even when the audio is working, because the audio is not guaranteed to work for every player.
Give the Player the Switches, and Label Them Clearly
The layered system is only useful if the player can choose which layers they receive. A single “SFX volume” slider does not let a sensitive listener remove the jump while keeping dialogue and music; it forces an all-or-nothing choice.
The documented solution is per-sound or per-category toggles, with descriptions that are specific enough for a player to know what they are turning off. A sound disabler tool for a visual novel engine describes the requirement directly: “Repetitive noises and long noises can be very bothersome to many individuals. Label them appropriately… ‘Birds chirping loop’ might be unbearable for a player, whereas a ‘Single owl hoot’ might be fine” . The same principle applies to the jump: the label should say what the sound is and what it does, not simply “SFX 3.”
The XAG audio guidance requires independent volume controls for at least music, voice-over, active sound effects, background/ ambient sound, narration, and voice chat . A jump sits ambiguously between “active sound effects” and “voice-over” depending on whether it carries a vocal grunt, and the practical choice is to give it its own category or to route it with the active SFX slider and make the visual alternative complete enough that the audio can be removed.
The accessibility design choices guide covers the channel-duplication principle in more detail; the jump case adds that the switch has to be narrow enough to remove the jump without removing everything else, and the label has to be specific enough that the player knows what they are removing.
A Configuration That Holds Both Constraints
The table below gives a starting configuration for a jump system that is designed for both hearing loss and auditory sensitivity. The values are starting points, and the two “switch” rows are the ones that make the system configurable rather than fixed.
| Property | Configuration | Which constraint it serves |
|---|---|---|
| Identity band | 500 Hz–2 kHz | Hearing loss: survives high-frequency loss |
| Transient | 10–20 ms attack; no 1–2 ms click | Sensitivity: below the startle threshold while still reading as immediate |
| Motion layer | Upward sweep into 2–4 kHz over 300 ms+; not a spike | Hearing loss: adds a second cue above the identity band; sensitivity: spread energy instead of a click |
| Variation | Shuffle, exclude last 1–2; pitch ±1–2 semitones | Sensitivity: prevents the repeated identical trigger |
| Visual | Pose and trajectory readable without audio; no sound-only information | Hearing loss: the audio can be removed entirely |
| Switch | Separate jump toggle or jump volume, not bundled with all SFX | Sensitivity: the aversive sound can be removed without losing dialogue or music |
The configuration is not a single sound. It is a system in which the audio is layered, the identity is placed where it survives, the transient is softened, the repetition is broken, and the visual channel can carry the event when the audio cannot. The whoosh and transient layering guide covers the two-layer construction from a character perspective; the accessibility version is that the same layering is what makes the sound adjustable without being redesigned.
A jump sound that works for every player is not a quieter or duller jump sound. It is a jump sound whose information is not trapped in a single band, a single transient, or a single channel. The player who hears it in full gets the character; the player who needs the midrange gets the event; the player who needs silence gets the visual. The design work is in making all three versions come from the same system.
