dB SPL stands for decibels sound pressure level. 

What does dB SPL mean?

dB SPL is a unit of measurement that is used to express the intensity of sound, or how loud a sound is. The reference pressure for dB SPL is 0.0002 dynes/cm^2, which is the threshold of hearing for humans.

dB SPL is measured using a sound level meter. A sound level meter is a device that measures the intensity of sound.

Is dB and dB SPL the same?

No, dB and dB SPL are not the same. dB is a unit of measurement that can be used to express a variety of things, such as sound pressure level, power, and voltage. dB SPL is a specific type of dB that is used to express sound pressure level.

What is a good dB SPL?

The “good” dB SPL level depends on the context. For example, a dB SPL level of 70 is considered to be a moderate noise level, while a dB SPL level of 100 is considered to be a loud noise level. In general, it is recommended to keep noise levels below 85 dB SPL to protect your hearing.

What does 100 dB SPL mean?

A dB SPL level of 100 means that the sound pressure is 100 decibels above the reference pressure of 0.0002 dynes/cm^2. This is considered to be a loud noise level and can cause hearing damage if you are exposed to it for a long period of time.

If you are concerned about your hearing, it is important to see an audiologist for a hearing evaluation.
