Cardioid Dynamic Microphone. The Neumann TLM 102, for instance, can take as much as 144 dB SPL! In audio, SPL plays an essential role because it is the correct way of measuring the perception of loudness. Obviously the higher it is, the easier it will handle loud sound sources such as a kick drum or brass instruments! Basically, the max SPL figure in the data sheet tells you how much level, how much volume a mic can take before it begins to distort audibly. Studio sound on stage. In other words, SPL measures the strength of a sound wave when emitted from a speaker. As an example, for a microphone with a sensitivity rating of 20 mV/Pa and a max SPL equal to 130 dB. The RE20 is an industry-standard large-diaphragm dynamic microphone, used worldwide on applications ranging from broadcast/VO to kick drum. In the old days, condenser mics were fairly limited in terms of SPL handling. The magnitude of the analog or digital output signal from the microphone with that input stimulus is a measure of its sensitivity. Some can actually be damaged from excessive levels. Happy customers, one piece of gear at a time! If you do notice distortion in your recordings, it’s often not the mic but your preamp or your AD-converter that clips. You may run into trouble with certain percussion instruments, though.

Many of the “younger” manufacturers measure at 1% THD, which results in (seemingly!) A common specification for microphones, max SPL indicates the highest sound pressure level a mic’s electronics can handle before the onset of distortion. Three polar patterns plus pad and low cut options make it adaptable to a wide range of applications. This reference point is but one characteristic of the microphone, by no means the whole story of its performance.The sensitivity of an analog microphone is straightforward and … As you can see, it’s really hard to find cheap ribbon microphones. Many older models barely reached a maximum SPL of 120 dB, but many newer models can handle enormous levels without distorting. The modern classic for vocals, spoken word, and more. Search this website. Broadcasters want clean sound. Many older models barely reached a maximum SPL of 120 dB, but many newer models can handle enormous levels without distorting. Specifies the max SPL (RMS and peak) below which the total harmonic distortion is less than 1%. Stunning Studio Gear That Will Stop You in Your Tracks. Hello, At the moment I'm using an (obviously expensive) B&K microphone with a dynamic threshold at 162dB, to be able to measure the acoustic pressure inside a clarinet mouthpiece. Microphones have a limit in terms of SPL after which they will begin to distort. 78 dB[2] Clipping Level. Ref. If the transducer is a condenser type, the diaphragm has a position in front of a backplate. Even though their SPL handling capability is not without limits, either, it rarely poses a problem in real life. At 100 Hz, the measured MAX SPL is 150 dB SPL and the electrical output of the microphone is 0 dB V or 1.0 volts. That’s a misconception! From the tweakiest techniques to the biggest ideas, our experts work hard to constantly supply inSync with a steady stream of helpful, in-depth demos, reviews, how-tos, news, and interviews. Rather, max SPL is the sound pressure threshold at which a microphone’s output signal begins to distort. Sound Pressure Level – SPL. A microphone with a higher sensitivity value has a higher level output for a fixed acoustic input than a microphone with a lower sensitivity value. Many professional condenser microphones have maximum SPL (Sound Pressure Level) input specifications which are 140 dB SPL or higher. The max SPL this combination was able to produce was 150 dB and the THD level recorded by a MD 421 was below 1% (produced by the driver not by the mic) So as a conclusion we can state the MD 421-II has no maximum SPL limitations for practical use.

With a linear response, low distortion and an extremely large dynamic range, these mics sound great no matter how challenging the environment. If stated on its own, for example "120 dB", it conveys significantly less information than having the self-noise and maximum SPL figures individually. A tambourine, for instance, is a lot louder than one would assume; at short distances it can easily reach SPLs of more than 120 dB. Just enter your loudspeakers Sensitivity (1w/1m) and … Sweetwater Sound Ribbon mics are especially susceptible to high SPL levels. Forum Index > Recording: Next oldest topic:: Next newest topic: Author Topic: Microphone Max SPL Specification; Jim Fogle. My thinking is that if the sensitivity is measured at 94 dB SPL and the max output is presumably 0 dBFS, then that 26 dBFS sensitivity would bring us up to 120 dB SPL. The Maximum SPL allows us to decide the proper use for the microphone. All professional microphones come with a product data sheet that show the voltage the mic will generate for a known reference dB-SPL (sound pressure level). Except for ribbon mics, dynamic microphones rarely come with a max SPL specification. Authentic, vibrant, transparent: The perfect high-resolution instrument microphone. Microphone Max SPL Specification. However, it can become an issue with older models due to aging effects. Maximum SPL levels will usually be accompanied by an associated THD (Total Harmonic Distortion) lev… The speaker sensitivity, typically expressed in decibels (dB) with 1 watt (or 2.83 volts across an 8 ohm speaker) measured on-axis one meter away. To obtain the microphone maximum output level in dBu, find your microphone's sensitivity rating on the left side and then move right until you are directly below your microphone's maximum SPL rating. It this an actual measurement or is it calculated? Here’s one ribbon … The … Being music makers ourselves, we love geeking out on all things gear. The mics are capable of handling extremely high SPL before clipping, which allows the mic to deliver high speech intelligibility even when the speaker gets excited and starts to speak VERY loudly. Microphone sensitivity is typically measured with a 1 kHz sine wave at a 94 dB sound pressure level (SPL), or 1 pascal (Pa) pressure. It characterizes the Max SPL of a transducer by setting limits on specific metrics (THD, Rub & Buzz, Perceptual Rub & Buzz, Input Voltage and Compression) and then driving the transducer at a series of standard ISO frequencies, increasing the stimulus level until the one of the limits is surpassed.
