"minecraft:apply_impulse" enchantment effect plays sound.

My failure. Its sound from item replace command.

When the "minecraft:apply_impulse" enchantment effect is triggered, a flutter-like sound is played.
Normally, sound playback is controlled by the "minecraft:play_sound" effect. Furthermore the "minecraft:explosion" effect includes a sound field that can be used to enable or disable audio. However, the "minecraft:apply_impulse" effect does not have such a field.

Therefore, I guess the sound is not an intended effect.

Below is the enchantment I used:

{
    "description": {"text":"impulse"},
    "supported_items": [],
    "primary_items": [],
    "weight": 1,
    "max_level":255,
    "min_cost": {
        "base": 0,
        "per_level_above_first": 0
    },
    "max_cost": {
        "base": 0,
        "per_level_above_first": 0
    },
    "anvil_cost": 0,
    "slots": ["mainhand"],
    "effects": {
        "minecraft:tick":[
            {
                "effect": {
                    "type": "minecraft:apply_impulse",
                    "direction": [0, 0, 1],
                    "coordinate_scale": [1, 1, 1],
                    "magnitude": {
                        "type": "linear",
                        "base": 1,
                        "per_level_above_first": 1
                    }
                }
            }
        ]
    }
}
