Microphones are vulnerable to loud sounds. Because sound is vibration, it can be very damaging. In fact, it is estimated that a typical eardrum will explode at 150dB SPL. But it can still be damaged.
The best way to avoid this problem is to be careful when working with microphones. It is advisable to avoid using the mic when you are working in an area with high humidity levels. This will prevent moisture from accumulating and will ensure that the mic is protected.
During the recording process, the maximum SPL of a microphone is measured. It is safe to record at these levels because the level of total harmonic distortion (THD) will be less than 0.5%. However, if the SPL is higher than this level, it will have a higher self-noise.
Thus, high SPL microphones should not be used during live performances. These microphones are sensitive to noise.
Generally, all types of microphones are resistant to tapping. The problem with this technique is that you have to be very careful not to damage the mic.
While a dynamic microphone can handle any practical sound pressure, a condenser microphone diaphragm can only withstand a low amount of impact.
But a ribbon microphone is especially fragile and should never be subjected to harsh impacts. Even a transient gust of air can destroy a condenser microphone.
If you are using a dynamic microphone, it is important to be aware of the fact that phantom power is a major factor in microphone health. The high phantom power can destroy the diaphragm and damage the mic.
To protect your microphone from this problem, check the specifications of the microphone and use it in a safe environment. A few tips will help keep your condenser mic in good condition.
Although most microphones are resistant to a high level of sound, some can be damaged by a loud guitar. Unlike a guitar, a dynamic microphone is more susceptible to induced magnetic radiation.
If you are recording an instrument, such as a choir, you may encounter a hum due to alternating magnetic fields. Similarly, a hum in a guitar may be caused by radiated magnetic fields.
While the components of a microphone will gradually wear out over time, most of them can withstand any practical amount of sound pressure. Moreover, the microphone will not be damaged by a high-level noise unless it is impacted by a transient gust of air.
A small blow of air, however, may damage a classic ribbon microphone. You should not tap your microphone if it is susceptible to this type of impact.
In reality, there is no way to determine how loud sounds can harm a microphone. The sound that is emitted from a microphone can affect its sensitivity to certain frequencies. If the sound is too loud, the microphone can become damaged.
To prevent this, it is necessary to avoid using the microphone in situations where it is exposed to hard noises. This will cause it to break. When you hear a tape, listen carefully and try to avoid making the noise too high.
Another way to check the microphone is to open it and visually examine its body for signs of damage. The XLR input pins must be in good condition. The microphone’s body should also be inspected for signs of damage.
If the mic has a sonic leakage, it should be repaired. Alternatively, it should be repaired and re-opened. A mic that has been dropped can be damaged by any loud noise.
The microphones can be damaged by tampering with loud sounds. If you are using a microphone in a studio, you can use a portable device to record the sound. A simple tapping will damage a dynamic microphone.
It is important not to bump or hit the microphone with a sharp object. Otherwise, you could destroy it. But if you have a condenser microphone, you should not be tempted to tap it.
