kuulamittari

Kuulamittari refers to a type of measurement tool used primarily in acoustics and audio engineering to quantify sound levels and frequencies. The term originates from Finnish, where *kuula* means "ear" and *mittari* means "meter" or "measurement device." This device is designed to simulate the human ear's response to sound, providing a more accurate representation of perceived loudness compared to general-purpose sound level meters.

Kuulamittari devices are often used in various applications, including environmental noise monitoring, workplace safety assessments, and audio equipment calibration. They measure sound pressure levels (SPL) in decibels (dB) and can be adjusted to match different frequency weighting curves, such as A-weighting (dBA), which aligns more closely with human hearing sensitivity. This weighting helps in evaluating noise levels that are more relevant to human perception.

In Finland and other Nordic countries, kuulamittari is a common term for sound level meters used in professional and regulatory settings. These meters are calibrated to ensure accuracy and compliance with international standards, such as those set by the International Organization for Standardization (ISO). They are essential tools for engineers, researchers, and safety professionals working to assess and mitigate noise pollution or ensure compliance with noise regulations.
