# PWR-030 — Quiet locomotion: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 17 min reading and worksheet pass Difficulty: Introductory Equipment: Basic stationery or digital tools — The three fictional recording rows below; Paper or spreadsheet; A calculator, optional; No walking task and no new recording Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G2; Focused research depth Automated method-quality band: Established Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context This pack supplies fictional measurements from recordings that already exist. The learner reports peak sound in each recording setup, checks which configurations can be compared, and keeps sound separate from force, tissue safety, stealth, and gait quality. Target outcome: Define quiet locomotion without inheriting mythology or broader claims. Explain what the current evidence supports and what it does not establish. Use the declared measurement boundary and recognise misleading proxies. Complete only the separately governed capability practice inside its declared limits. Make a retention, transfer, maintenance, provider or stop decision without overclaiming. ### Authority and setup conditions - Do not make a new walking take, change speed, change foot strike, remove an aid, or try to walk quietly for this exercise. - Use the fictional data below or an ordinary recording that already exists and was made safely. - Peak dBA is a sound measurement in a declared setup; it is not ground-reaction force, loading rate, tissue safety, or a judgement about an aid or prosthesis. ### Required or supplied materials - The three fictional recording rows below - Paper or spreadsheet - A calculator, optional - No walking task and no new recording ### Supplied fixture These are fictional A-weighted peak readings from three already-recorded clips. The descriptive statistic is the median, not an arithmetic energy average of decibels. | Clip | Surface | Footwear and aid | Speed m per s | Microphone distance m | Meter mode | Five peak readings dba | | --- | --- | --- | --- | --- | --- | --- | | A | Vinyl | Walking shoes; no aid | 1.2 | 1 | Same fictional peak-dBA meter | 62; 64; 63; 61; 65 | | B | Carpet | Walking shoes; no aid | 1.2 | 1 | Same fictional peak-dBA meter | 55; 56; 54; 55; 55 | | C | Vinyl | Boots; cane present | 1.4 | 0.5 | Same fictional peak-dBA meter | 68; 69; 67; 70; 68 | ## 1. For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode,… For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode, and the five peak readings. Why: “For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode, and the five peak readings” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: A legible entry directly completes “For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode, and the five peak readings” and records the requested condition, decision or boundary without adding a new claim. Accessible alternative: Complete the same research action — “For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode, and the five peak readings.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “For every clip, copy surface, footwear, aid, speed, microphone distance, meter mode, and the five peak readings” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Sort the five readings and select the middle value as the median… Sort the five readings and select the middle value as the median peak dBA. Why: “Sort the five readings and select the middle value as the median peak dBA” fixes the exact Quiet locomotion configuration or decision before later observations are compared. Success check: The learner can verify “Sort the five readings and select the middle value as the median peak dBA” from the declared materials, position or recorded choice before continuing. Accessible alternative: Complete the same research action — “Sort the five readings and select the middle value as the median peak dBA.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The learner can verify “Sort the five readings and select the middle value as the median peak dBA” from the declared materials, position or recorded choice before continuing.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Calculate the range as maximum minus minimum Calculate the range as maximum minus minimum. Why: “Calculate the range as maximum minus minimum” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: The work shows the value requested by “Calculate the range as maximum minus minimum”, retains the supplied units or signs and leaves any unsupported value unknown. Accessible alternative: Complete the same research action — “Calculate the range as maximum minus minimum.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The work shows the value requested by “Calculate the range as maximum minus minimum”, retains the supplied units or signs and leaves any unsupported value unknown.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Compare clips only after checking which configuration fields match Compare clips only after checking which configuration fields match. Why: “Compare clips only after checking which configuration fields match” isolates the named evidence distinction so the learner can interpret Quiet locomotion without extending the claim. Success check: The output directly answers “Compare clips only after checking which configuration fields match”, names the relevant distinction and stays within the supplied record. Accessible alternative: Complete the same research action — “Compare clips only after checking which configuration fields match.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The output directly answers “Compare clips only after checking which configuration fields match”, names the relevant distinction and stays within the supplied record.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Describe the observed sound difference without inferring force or safety Describe the observed sound difference without inferring force or safety. Why: Keep this exact Quiet locomotion action explicit and reviewable: “Describe the observed sound difference without inferring force or safety.” Success check: Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Describe the observed sound difference without inferring force or safety.” Accessible alternative: Replace spoken or audio cues with visible text, captions or haptic timing while keeping the same sequence and success check. Use text-to-speech, enlarged text, keyboard navigation, shorter sessions, a support person or an equivalent non-practical record format as needed. Accessibility changes must not enlarge practical authority. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Finish with a bounded conclusion and a list of non-claims Finish with a bounded conclusion and a list of non-claims. Why: “Finish with a bounded conclusion and a list of non-claims” establishes the exact Quiet locomotion question or boundary that every later comparison must preserve. Success check: Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Finish with a bounded conclusion and a list of non-claims.” Accessible alternative: Complete the same research action — “Finish with a bounded conclusion and a list of non-claims.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Finish with a bounded conclusion and a list of non-claims.”” Do not convert the research task into capability practice.
