STIHL MS 250 مقابل MS 251 C-BE|مستوى ضغط الصوت
مستوى ضغط الصوت (SPL) يتم قياسه بالديسيبل, with lower numbers indicating a quieter, softer sound. The “A” in STIHL stands for “Attenuator,” which is the device that divides the music into different frequencies, turning the violin into different pitches. The “C” in C-BE stands for “Compressor,” and it’s used to control the overall loudness of an instrument by controlling how much of the high or low end frequencies are being amplified.
MS 250 has the standard sound pressure level of 210 ديسيبل, بينما MS 251 C-BE has a sound pressure level of 230 ديسيبل. As the sound pressure level you can listen to at home depends on things like where you live and how close to the source of the noise you are. As such, it’s preferable to look at it in terms of decibels per second rather than in absolute numbers (which don’t work very well).
There are certain categories of noise produced by the engine assembly, which are called Sound Pressure Levels (SPL). The higher-end MS 250 و MS 251 C-BE products have an integrated sound system that is optimized for each particular application. It’s also worth mentioning that the sound system of a machine is not just limited to the noise produced on the exhaust side. A modern silencer can produce noise in all directions, including upwards, in order to prevent any irritability from being caused by noise generated from other sources.
