CDM Group appoints Laurence Carels as new CEO

OVERIJSE, July 17, 2020 – CDM Group’s Board of Directors announces the appointment of Laurence Carels as Chief Executive Officer as from July 17, 2020. Laurence Carels, who joined CDM Group thirteen years ago, succeeds Patrick Carels who has led the company successfully for the past 34 years.

Being a family business, CDM Group has always been a big part of Laurence Carels’ life. From an early age she helped out with the administration and logistics, and in 2007 she joined the accounting department after obtaining her Master’s degree in Applied Economics at the University of Leuven. In 2010 Laurence Carels moved to the United States to set up a new subsidiary while at the same time working for a local accounting firm, active in helping European companies to set up their business abroad. Early 2017, Laurence Carels moved back to Belgium to take up the position of Chief Financial Officer (CFO), leading financial operations, risk management and regional finance teams. Laurence Carels brings with her both an extensive background in corporate finance and a deep appreciation for CDM Group and its unique mission to make this world a quieter place through the design and manufacturing of innovative noise and vibration isolation solutions.

On being appointed Laurence Carels stated: “I’m excited to have been offered the opportunity to lead CDM Group at such an important time in its development. CDM Group has a great global culture, amazing market capability and a strategy that has seen us grow solidly in recent years; I look forward to building on this success and I’m eager to take on this new challenge, assisted by a passionate team of collaborators and take CDM Group to the next level, respecting the values, vision and mission that have brought this company where it stands today.”

Patrick Carels, who will take on a new role within CDM Group as Chairman of the Board of Directors, considers the appointment of Laurence Carels a logical choice, as she has years of relevant experience
and has been prepared to take on this task. She knows the company, the market, and its customers. “We are fortunate to have someone of Laurence Carels’ caliber and experience step up to lead CDM Group,” said Patrick Carels. “We are at a critical moment and we need renewed leadership to successfully implement our strategy, take advantage of the market opportunities ahead and lead CDM Group in its next phase of growth.”

CrossFit GVA – Acoustic Weight Drop Test


Exercise is noisy. Whether it is the percussive noise from cardio equipment or the booming low frequency sound from weight impacts, all these activities create a significant amount of airborne and impact sound.

Dropping even a relatively small weight, such as a kettlebell, from a height as low as a couple of feet will create huge vibrations which can easily be heard in adjacent rooms, leading to noise complaints from neighbors.

Getting the right flooring is the number one step gym owners should take to minimize gym noise. CDM-GYM dry and lightweight floating floor solutions are specially designed to provide superior sound reduction. These systems are performance-engineered to control vibrations, minimize low-frequency impact noise, and reduce the transmission of audible structure-borne sound, allowing gym owners and tenants to happily co-exist.

Jon Ingram, owner of CrossFit GVA in Geneva, Switzerland, found his business in jeopardy when noise complaints began to come in. The gym, which is surrounded by residential apartments and is open until late at night, generated a lot of noise, something that the neighbors didn’t appreciate.

To resolve the problem, CrossFit GVA turned to CDM to install a CDM-GYM acoustic floor that would effectively isolate the building. Under the watchful eye of the owner and an acoustician we decided to install a mock-up on which several in situ weight drop tests were performed.

Noise measurements in several adjoining apartments have shown that CDM-GYM floating floors significantly reduce the volume as the energy of the impact is dispersed over a longer time frame into the flooring. Even the biggest impact of a barbell (1275 N.m) falling from shoulder height was absorbed by the acoustic floor system, convincing the gym owner of the effectiveness of our CDM-GYM solutions.

Railway induced vibration: a threat to our health

More and more people rely on public transport to commute to work or go about their daily business, a green trend that is stimulated by the European Commission that aims to increase rail capacity by 50% in order to reduce greenhouse gas emissions.

Nevertheless, on a more local level this increase in rail traffic may have negative implications for the quality of life and individual health of populations living close to railways.

A recent study performed among the citizens of the Västra Götaland and Värmland regions in Sweden shows that vibrations from rail transport are experienced through a number of senses. The chronic nature of exposure to this environmental stressor was a recurring topic. The inability to avoid or mitigate vibrations has been proven to have negative repercussions for one’s health and well-being.

The proximity to railways and the exposure to constant vibrations causes a series of illnesses such as elevated blood pressure, anxiety, insomnia, diabetes and cardiovascular disease.

In 2011 the World Health Organization already warned that 1.8% of myocardial infarctions can be attributed to exposure to road traffic noise and only a few months ago they stated that around 466 million people worldwide have disabling hearing loss, and it is estimated that by 2050 over 900 million people will have disabling hearing loss caused by noise pollution.

We at CDM Group are constantly trying to “make our world a quieter place” by developing new and effective solutions to decouple entire buildings or building layers, preventing harmful vibrations from causing harm to both infrastructure and public health.
