Personal sound amplification products are ear-level amplification devices intended for use by persons with normal hearing. The output levels of 27 PSAPs that were commercially available in Europe were analyzed in 2014. All of them had a maximum output level that exceeded 120 dB SPL; 23 (85%) exceeded 125 dB SPL, while 8 (30%) exceeded 130 dB SPL.
Music played at 85 decibels, or level of sounds, for prolonged periods of times can cause hearing damage, for instance, sound levels at some rock concerts can reach 110-120 A-weighted decibels, and at those levels, the maximum daily limit set by most standards and regulations can be reached in less than one minute of exposure.

In modern recording, this range is often limited through dynamic range compression, which allows for louder volume, but can make the recording sound less exciting or live. [50] The dynamic range of music as normally perceived in a concert hall does not exceed 80 dB, and human speech is normally perceived over a range of about 40 dB. [28]: 4
To keep the volume at a safe level, limit the volume to 60-70% of the maximum volume. A good rule of thumb is that you should still be able to hear a person talking at an arm’s length from you.
1 LU corresponds to the relative measurement of 1 dB on a digital scale. LU can also express the difference in level from the target level. [5] In a loudness meter implementing EBU Mode: Reference level = −23 LUFS = 0 LU A programme with an integrated loudness of −26 LUFS measures −3 LU in EBU Mode (i.e. is 3 LU quieter than the target ...
Signal-to-noise ratio (SNR), however, is the ratio between the noise floor and an arbitrary reference level or alignment level. In "professional" recording equipment, this reference level is usually +4 dBu (IEC 60268-17), though sometimes 0 dBu (UK and Europe – EBU standard Alignment level).
In music, the dynamics of a piece are the variation in loudness between notes or phrases.Dynamics are indicated by specific musical notation, often in some detail.However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece.
