Contemporary noise control trends in Finnish Mechanical Engineering/Manufacturing

Application of add-on noise control materials (esp. absorption materials) are being minimized. At the same time, the applications of high strength steels (and other alloys) is increasing. These two trends, separately and combined, will greatly increase the need for "good engineering design" and machinery acoustics.

Third trend has already been forming for a while. Due to various engine Tier levels the need for cooling has been increasing. When combined with space limitations, the increase in cooling noise and lack of cooling performance are an issue. As a reminder, this is our field of unique specialty.

Fourth, potential trend is related to the increasing environmental awareness and individual comfort. Machine and process noise are reduced below the official requirements.
