What is a good max SPL?
Traditionally, the threshold has been a total harmonic distortion (THD) of only 0.5%. Many older models barely reached a maximum SPL of 120 dB, but many newer models can handle enormous levels without distorting. The Neumann TLM 102, for instance, can take as much as 144 dB SPL!
What is the difference between SPL and dB?
Thus, in order to be meaningful, your audiologist indicates which decibel scale she used. The two most commonly used scales are the SPL (Sound Pressure Level) and the HL (Hearing Level) scales. Sound meters are calibrated in dB SPL….
| Frequency | ||
|---|---|---|
| Hz | dB SPL | dB HL |
| 125 | 45.0 | 0 |
| 250 | 27.0 | 0 |
| 500 | 13.5 | 0 |
Does 0 dB HL mean no pressure?
Decibels in hearing level, or dB HL, is com- monly used in audiology because it refers to the decibel level on the audiometer. The reference level for dB HL is “0,” which is related to the average threshold in decibels sound pressure level (dB SPL) for the average, normal-hearing listener.
What should maximum sound pressure be on Mic?
As long as you don’t record drums, your mic’s maximum sound pressure level is rarely an issue. You may run into trouble with certain percussion instruments, though. 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.
What does a maximum sound pressure level ( max SPL ) indicate?
There is some confusion as to what “max SPL” means. Some people believe this is the maximum sound pressure level the respective microphone can withstand without breaking. That’s a misconception! It’s merely the maximum sound pressure level this mic can take without distorting.
How to calculate sound pressure and sound pressure level?
For example, if we measure a sound pressure of 0.4 Pa, we can determine the SPL in dB: So a pressure change of 0.4 Pa equates to about 86 dB. In case you do not want to do the math on all of our examples above, here is that same table, now including sound pressure level.
What’s the increase in sound pressure of 6 dB?
Doubling sound pressure (in Pa) – increases sound pressure level (in dB) with 6 dB (or 20 log (2)). The chart below shows the sound pressure level decibel scale compared to the sound pressure Pascal scale.
