This sounds like Cranmer’s rantings against the Canon
Cranmer ordered his entire service to be said “playnly and distinctly”
Rubric in the 1549 Communion Service
"If anyone says that the rite of the Roman Church prescribing that a part of the Canon and the words of consecration be recited in a low tone of voice, should be condemned… **let him be anathema." **
Council of Trent XXII session
Condemn -To pronounce to be wrong; to disapprove of; to censure.
[1913 Webster]
You should remember that a silent Eucharistic Prayer is not something exclusive to the TLM. In the Eastern liturgies, not only is the Eucharistic Prayer said inaudibly (except for the words of institution) — so is the Preface.
The silent Canon, “betokens the Consecration and Sacrificial Act to be an exclusively priestly function.**
*The Holy Sacrifice of the Mass *(St. Louis, Mo., 1908), p. 582.”
“The priest enters the sanctuary of the canon alone. Up till now the people have thronged round him, their songs at times accompanying him in the fore-Mass. But the songs have become less frequent, and after the steep ascent of the Great Prayer they have come to an end in the Triple *Sanctus. A *sacred stillness reigns; silence is a worthy preparation for God’s approach. Like the High-priest of the Old Testament, who once a year was permitted to enter the Holy of Holies with the blood of a sacrificial animal (Hebr. 9:7), the priest now separates from the people and makes his way before the all-holy God in order to offer up the sacrifice to Him”

My favorite quote from Dr. Gihr
“In every Host there are miracles, as numerous as stars in the firmament,— yet not the slightest trace of the wonders appears externally. With all this the ecclesiastical rite harmonizes perfectly. The holy silence is quite suited to indicate and to recall the concealment and depth, the incomprehensibleness and ineffableness of the wonderful mysteries that are enacted on the altar. Silent prayer is related to religious silence, and, therefore, expresses the humility, reverence, admiration, and awe wherewith the Church administers and adores the Mystery of the 'Altar.** “The Lord is in His holy temple; let all the earth keep silence before Him” (Hab. 2:20)**. The sight of the priest at the altar, communing amid profound stillness with God alone, is, therefore, also an excellent means afforded to arouse and promote in those who are present the proper dispositions, with which they should admire, adore, and offer along with the priest So grand and sublime a Sacrifice. Quam terribilis est haec hora!—thus does the deacon cry out to the people in the Syrian liturgy—“How terrible is this hour!” While the tremendous Sacrifice is being accomplished on the altar, all present should be immersed in silent contemplation and in devout meditation of the divine Mysteries.”
