Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make zero hence "diluting" the noise.
Sony WH 1000XM3 allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Sony WH 1000XM4 too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that suits your commute or that enhances your relaxation time.
Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The Sony WH 1000XM3 sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Both of these devices have passive noise reduction which means that also the Sony WH 1000XM4 isolates you from ambient noise instead of actively using technology to cancel it out. Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through.

both devices produce equal treble
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, Sony WH 1000XM3's measurement is 104.5dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source. Sony WH 1000XM4's sound pressure level measurement is 105dB/mW.
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sony WH 1000XM3 driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass. Sony WH 1000XM4 driver unit is 40mm in diameter,
making both devices similar in how loud their sound gets
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce better sound. Impedance is the device's resistance to the electromagnetic current, when electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms.
