Measurement, characterization and modeling of acoustic materials
We are looking for a doctoral researcher (PhD candidate) to study porous materials. The main emphasis in the PhD work would be on measurements, characterisation, and modelling of porous materials in close collaboration with the researchers in chemical engineering. Moreover, the aim is to go beyond the traditional impedance tube and reverberation chamber measurement techniques and develop some novel ways to characterize parameters for modelling of porous acoustic materials.

The research will be done in the Virtual Acoustics research team, led by Prof. Tapio Lokki. The team is well known on the work on room acoustics, in particular on studies on concert halls, but our recent interests is to work on bio-fibre based porous acoustic materials. The goal is to develop, together with researchers of functional materials, carbon-negative acoustic materials that could be used in building and room acoustics.
Project Background
The core idea of the research project is to substitute current market standard insulator materials, rock and glass wool, with biowaste-based materials that absorb sound effectively. As proof-of-concepts, we will develop silent air duct and silencer for air conditioning pipes that bind the carbon of biowaste to buildings for decades. The proposed research combines distinct expertise of Chemical and Acoustical Engineering and aims at paradigm shift in construction industry by demonstrating that bio-based products can exceed the performance of state-of-the-art materials in multiple occasions in building materials. Industrial scalability and circular economy, with the prospect of providing urgently needed carbon-negative construction materials, are at the core of this multidisciplinary research.
Candidate Profile
All candidates must be fluent in spoken and written English. An ideal candidate has an M.Sc. in engineering (e.g. acoustics, computer science, building acoustics, physics, material sciences).
  • Knowledge of porous acoustic materials, practical signal processing (matlab or python), and room and building acoustics is a strong advantage.
  • Very good in scientific writing and communication skills
  • Eligible for PhD study at Aalto University 

The nominal time for PhD in Aalto University is 4 years. Both female and male candidates are invited to apply. The applicant needs to be eligible for PhD study at Aalto University (

Job conditions
The host organisation will appoint the successful applicant under an employment contract with a competitive salary according to EU regulation, including social security. The duration of the contract is, at least, XX months. The expected starting date is in September 2022, but other possibilities are negotiable. The salary is xxx
This position includes doctoral studies. The successful applicant must register for the PhD program at Aalto University School of Electrical Engineering. The nominal duration of the doctoral studies in Finland is 4 years.
The position will be filled for a period of 4 years (2+2). The starting date is in September 2022 or as mutually agreed. The salary will be based on both the job requirements and the employee’s personal performance in accordance with the salary system of Finnish universities. The starting salary for a PhD student is approximately 2600 EUR/month.
We offer a wide range of staff benefits, such as occupational health care, flexible working hours, excellent sports facilities on campus and several restaurants and cafés on campus with staff discounts. The position is located at the Aalto University Otaniemi campus which can be easily reached by public transport.

The Aalto Acoustics Laboratory
The Aalto Acoustics Lab is a multidisciplinary research center of the Aalto University. The Acoustics Lab has world-class facilities including 3 anechoic rooms (one of them equipped with 45 loudspeakers), variable acoustic room, standard listening room and a lot of measurement equipment. Our research and teaching covers wide range of topics, although the main focus is on audio processing, room acoustics, and spatial sound technologies.

Aalto University is a multidisciplinary community, where science and art meet technology and business. Aalto University offers to the selected candidate an innovative and ambitious research environment with the best scientists in their fields. Aalto, having about 20 000 students and 4 500 employees, is in Espoo, 11 minutes with metro from downtown of Helsinki. Finland is known for its excellent social security system and beautiful nature. For the selected candidate assistance for finding accommodation can be given.
