My mission is to improve the quality of products like hardware and software.
I have been working as a vibroacoustic engineer for 15 years. I gained my experience in the automotive industry and in IT. In my career, I have made many improvements in products and software. I also coordinate building mobile applications and software.
As a freelancer:
1. I worked with Polish brands Reqnet (recuperators) and Izzifast (heat pumps and hydraulic cabinets) to improve the acoustics of these products.
2. I developed the vibroacoustics process at Aquarius, an Israeli startup producing modern power generators based on two-stroke engines.
3. I audited and supported the process of vibroacoustic detection of loud sunroofs for passenger cars at Inalfa Roof Systems.
4. I co-created a modern Instalator365 office management program for construction companies.
At the beginning of my career in the automotive industry, I worked at Nidec Motors & Actuators Ltd as an acoustic quality engineer in the series production of electric motors. One of my successes has been the removal of subjective acoustic control by operators. Thanks to this change, Ferrari, our client, lost grounds for a knocking steering column complaint. This improvement had a positive effect on the production statistics.
For 7 years I worked at research and development center BorgWarner Ltd – I dealt with reducing the noise levels of turbochargers. I was one of the first engineers at the Technical Center. I built and equipped the nvh department in this company. The first turbine I tested was discontinued after a few years. However, there are also those that will be assembled on production lines of factories in various parts of Europe only in 2020. My job focused on developing engine designs for both small passenger cars and large luxury cars and even trucks. I have tested both gasoline engines, ranging from 1 liter (3 cylinders) to 2 liter engines, and compression ignition engines, ranging from small 1.3 liter to 8 liter truck engines. I also had the opportunity to develop difficult designs for two-stage turbochargers. I shared my knowledge and gained experience with three engineers, whom I implemented in the process of developing the acoustics of turbochargers.
While working in the Rzeszów branch of the company, I comprehensively dealt with acoustics for many engine-turbocharger projects. I was the person responsible for contacting dedicated turbochargers for manufacturers of several recognized car brands. Together with the acoustics engineers of the manufacturers, we have set the noise and vibration limits for turbochargers. Together with them, I checked prototype turbines prepared especially for these purposes on test tracks. I investigated the influence of bearings, temperatures, imbalances, pressures, various types of oil viscosities. My knowledge and experience contributed to the optimization of the production of many structural elements of the turbocharger. I have also improved the balancing processes for prototypes and serial products. I also had the opportunity to introduce a very important innovation in testing turbochargers. I used the lean startup method to develop the idea. I managed to persuade corporate management to invest in my idea, which was to replace very expensive tests on cars with tests on components. As a result, the company will gain significant savings.
In 2019, working as an NVH engineer for BorgWarner, I wrote an article for the newspaper “Automoto technika”.
Before I started working in the automotive industry, I dealt with noise simulation for b2b, b2g and b2c clients for 4 years.
I am constantly looking for improvements in the field of acoustics and vibroacoustics. One of my favorite topics is psychoacoustics, which tells us about our feelings regarding noise.
I am interested in graph databases and artificial intelligence algorithms. Privately, I have been passionate about creating music for years, now I am interested in relaxing & meditation music. I do ski touring, splitboard, MTB enduro, yoga and meditate regularly.
We are witnessing a constantly accelerating development in all aspects of homo sapiens activity. Science is exceptionally brilliant and often surprisingly successful in almost all areas. Thanks to such dynamic progress, especially in technology, modern man has an exceptionally wide access to newer and newer devices that improve his life. Without many of them, we are not able to imagine our everyday life, and it would probably be simply impossible. However, along with a number of useful aspects of their work, sometimes there are side effects as well. These include, among others noise or vibrations. While we complain about noise often and loudly, we usually treat vibrations as something obvious in the surrounding environment. When we come into contact with them every day, we do not realize that they have a more or less harmful effect on our health, the efficiency of machines or the strength of the structure. Being in noise causes chronic stress. Another important aspect related to acoustic waves and vibrations is sound therapy. Properly selected frequencies can bring the mind into a state of relaxation or concentration.
My offer is addressed to production companies from the automotive and aviation industries as well as the machinery and equipment manufacturing sector. Most manufacturers produce devices whose derivative is sound pressure levels and doesn’t work with nvh engineer, struggling with noisy product issues.
Nvh engineer in daily work is responsible for noise and vibrations limits development in r’n’d or in serial production.
His job is to establish a strategy whereby the end customer will be satisfied with the sound of the product while maintaining high production and sales rates.
My business is consultancy and measurements aimed at reducing noise and introducing possible improvements in the product. In my work, I use advanced methodologies, the same as those that I implemented in the process of developing the acoustics of turbochargers, electric engines, power generators, sunroofs, heat pumps, recuperators.
More and more often I offer support in the development of software and mobile applications.
I provide creative technical content in social media. My help in this area consists in creating interesting promotional materials related to the currently performed task and promoting the client.
I sell soundhealing music.
The Focusly app is a powerful tool that can help users achieve their goals of developing and achieving a state of relaxation. The use of acoustic techniques can help to improve concentration, reduce stress and anxiety and increase creativity.
I was recently commissioned to measure the noise of a Refrigerator. A few years ago I myself had to deal with a noisy fridge in a bedsit. I couldn’t sleep and was tired in the morning.
Nowadays, I appreciate acoustic comfort and silence, so I would definitely check what the noise level of a new fridge is in my bedroom 😊.
The holiday season has come to an end, and with it a time for reflection. For the second year in a row, I decided to go alone with my children to Croatia. We had lots of different adventures involving the car, camping. Trips like this are incredibly inspiring, relationship-building and great for improving soft skills. Definitely not an easy venture, but well worth the experience.
When coming up with the term ‘Noisehacking’, I was referring to the term Biohacking. Biohacking and noisehacking are two different approaches to optimising our lives in different areas. The slogan also perfectly sums up the type of some of the features in the music in the meditation and development app Focusly that I have been working on.
I performed in front of the cameras again and I am slowly starting to like it. I carried out noise measurements for two heat pumps and discussed the results. The Youtube channel “izziinstalacje” already has 70k viewers and 18M views.
Over the last few months I’ve had the opportunity to work with Focusly on the music section of the Focusly app. This has also been a great fit with my passions as it relates to meditation, development, stress reduction and music.
Global organizations are forcing the construction of increasingly fuel-efficient cars, reducing the consumption of natural resources. Usually meeting such requirements leads to optimization of car design. Very often it concerns the generation of noise, which can sometimes be a nuisance when driving a car.
Noise becomes a real problem for the end customer and is cascaded by car corporations throughout the supply chain. As a result, OEMs are changing their cars, and suppliers and sub-suppliers must also follow developments imposed from above.
🥱 Bored with “Lean” and “Six Sigma” – methods common in Automotive, I was looking for knowledge on how to approach problem solving innovatively. Methodological optimization and “nibbling” percentages is not always the right solution, when it’s begging to be “turned upside down”. My creative approach in problem solving was ‘somehow’ intuitive, based on ‘some’ experience, being ‘somehow’ more open to solutions and ‘somehow’ having flashes of ideas. Often this approach led me to come up with ‘some’ solution. However, I was also often left with an idea and the thought “what next?”.
“The world that we have created is the result of our thinking. It is not possible to change it without changing our thinking” Albert Einstein
Relaxation music has changed my way of thinking….
For several months I developed programming software for small and medium-sized construction companies. This project taught me a completely different approach to developing web applications. I had the opportunity to test the demo version and implement the first releases with the first customers. I also had an influence on the development of the application’s features based on feedback from the market.
I have had 5 public speaking appearances in 2022. Once when I worked in a corporation I liked to train and show my papers to clients. My presentations were technical, sometimes very long. Mostly about the noise, vibration – NVH engineering. I never had the opportunity to prepare a presentation in the form of a startup pitch, a product pitch, a sales pitch, a marketing pitch, for a product that is not yet there and to speak in front of a large group of people.
I have had the opportunity to test the noise and vibration (nvh) of many different cars, at different stages of development. Some were early prototypes and others were series cars.
I’ve programmed in many languages in the past c, c++, java, sql and many others. I didn’t really like any of these languages. I’ve always liked databases and tables. What NEO4J did exceeded my wildest expectations. Using the CYPHER language in this database, it was possible to successfully build the MVP of the artist billing program.
The clever nvh engineer always has a bundle of zip ties with him, even in the mountains. They saved my day….
The limit to solving problems with a piece of plastic is only your imagination. NVH engineer should be very creative.
Towing dyno – is a car dyno in the form of a trailer. The load it generates is able to stop the car in a fraction of a second. I drove the car myself, took care of the trailer and took measurements of vibroacoustic. For NVH Engineer towing dyno substitutes hills.
The automotive business looks like that in Germany they have research and development of products, and in Poland these products are manufactured. In this post I describe an interesting example showing the reverse trend in the automotive industry. Polish doesn’t mean it’s worse…
I have made some nvh improvements on heat pumps and on recuperators. I had first performance in front of camera in construction video blog.
Vehicle nvh engineering is my passion. I did nvh measurements on brand new luxury car.
As very experienced nvh engineer I have decided to share my knowledge.
