Some tones are masked by background noise, while others stand out clearly. In some cases, the tones are caused by resonances, whereas in others they are related to orders generated by components such as the engine, tyres, turbochargers, or auxiliary systems.\nObjective\nThe objective of this work is to evaluate different tonality metrics using vehicle recordings. Assess which metrics provide objective measures that best reflect subjective perception.\nScope\nThe work package includes:\nLiterature review - Assessment of different tonality metrics \nYou will be provided with recordings representing different types of tonal sounds perceived in ICE and BEV vehicles. Evaluating the collected sounds using selected tonality metrics.\nPlanning and conducting listening tests (jury tests) to correlate subjective evaluations with objective metric results.\nAnalyzing the results and identifying the most suitable tonality metrics for different applications.\nWriting a final report and presenting the results to TRATON.\nEducation\nMasters student with focus on Psychoacoustics, Vehicle Acoustics or Technical acoustics.\nBackground in signal processing - MATLAB/ Python and interest in sound quality evaluation will be considered a plus.\nNumber of students: 1 or 2\nStart date: Jan/Feb 2027\nEstimated time needed: 20-25 weeks\nContact persons and supervisors\nAditya Thombare, +4670086577, \nMartin Jerling, +700812659, \nApplication:\nYour application must include a CV, personal letter and transcript of grades\nA background check might be conducted for this position. We are conducting interviews continuously and may close the recruitment earlier than the date specified.","description_format":"text","description_chars":1869,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-11T21:07:21Z"}],"visa":[],"liveness":{"score":37,"band":"fade","label":"Fading","p_open":1,"p_active":0.665,"p_room":0.55,"age_days":16,"expected_fill_days":16,"reasons":["conf:0","velocity","win:tail","comp:brand"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/scania-master-thesis-evaluating-tonal-noise","json_url":"https://alion.io/job/scania-master-thesis-evaluating-tonal-noise.json","meta":{"generated_at":"2026-10-25T00:54:15Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1408,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":445730},"rest":"https://alion.io/mcp/rest/get_company?id=445730"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fscania-master-thesis-evaluating-tonal-noise"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fscania-master-thesis-evaluating-tonal-noise"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fscania-master-thesis-evaluating-tonal-noise"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/scania-master-thesis-evaluating-tonal-noise\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fscania-master-thesis-evaluating-tonal-noise"}]}
