When it comes to describing the sound level, 'louder' is just one of the many words you can use. If you need more colorful and descriptive words to communicate the same idea, you can try 'thundering,' 'thunderous,' 'blaring,' 'earsplitting,' and 'piercing.' If you want to emphasize the force or intensity of the noise, go for 'deafening,' 'booming,' 'roaring,' 'resounding,' or 'cacophonous.' However, if you don't want to sound too negative, you can choose more neutral or positive words like 'prominent,' 'pronounced,' 'vigorous,' 'bold,' 'bright,' or 'distinct.' Whatever words you choose, remember that it's essential to convey the right message and tone.
