Bhagavad-gita As It Is

BG Chapters 1 - 6

A brahmacārī hears only words concerning Kṛṣṇa consciousness, he restrains himself from the vibrations of material sounds, and his hearing is engaged in the transcendental sound vibration of Hare Kṛṣṇa, Hare Kṛṣṇa

BG 4.26, Purport: A brahmacārī hears only words concerning Kṛṣṇa consciousness; hearing is the basic principle for understanding, and therefore the pure brahmacārī engages fully in harer nāmānukīrtanam—chanting and hearing the glories of the Lord. He restrains himself from the vibrations of material sounds, and his hearing is engaged in the transcendental sound vibration of Hare Kṛṣṇa, Hare Kṛṣṇa. Similarly, the householders, who have some license for sense gratification, perform such acts with great restraint.

Srimad-Bhagavatam

SB Canto 3

If one accepts the holy name of Viṣṇu to be a material sound vibration, that is also an offense

SB 3.15.25, Purport: The holy name of Viṣṇu is the most auspicious name, and His pastimes are also nondifferent from the holy name of the Lord. There are many foolish persons who say that one can chant Hare Kṛṣṇa or chant the name of Kālī or Durgā or Śiva because they are all the same. If one thinks that the holy name of the Supreme Personality of Godhead and the names and activities of the demigods are on the same level, or if one accepts the holy name of Viṣṇu to be a material sound vibration, that is also an offense. The third offense is to think of the spiritual master who spreads the glories of the Lord as an ordinary human being.
